Example Question #81 : Understand Independent And Dependent Variables: Ccss.Math.Content.6.Ee.C.9

Select the table of values that represent the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle 16 m - 14 = n

Possible Answers:

Correct answer:

Explanation:

In the equation \displaystyle 16 m - 14 = n\displaystyle {m} is the independent variable and \displaystyle {m} is the dependent variable. This means, as we manipulate \displaystyle {m}\displaystyle {n} will change.

Because we are given tables in our answer choices, we can plug in the given value for \displaystyle {m} from the table and use our equation from the question to see if that equals the value given for \displaystyle {n} in the table.

Let's start by testing values from the following table:

\displaystyle {16(5)+-14=67}

\displaystyle {80+-14=67}

\displaystyle {66\neq 67}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {16 m - 14 = n} ; thus, this answer choice is not correct and can be eliminated.

Next, let's test values from the following table:

\displaystyle {16(10)-14=146}

\displaystyle {160-14=146}

\displaystyle {146=146}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {16(13)-14=388}

\displaystyle {208-14=388}

\displaystyle {194\neq 388}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {16 m - 14 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {16(8)-14=114}

\displaystyle {128-14=114}

\displaystyle {114=114}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {16(10)-14=146}

\displaystyle {160-14=146}

\displaystyle {146=146}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {16(16)-14=253}

\displaystyle {256-14=253}

\displaystyle {242\neq 253}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {16 m - 14 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {16(1)-14=2}

\displaystyle {16-14=2}

\displaystyle {2=2}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {16(11)-14=162}

\displaystyle {176-14=162}

\displaystyle {162=162}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {16(16)-14=242}

\displaystyle {256-14=242}

\displaystyle {242=242}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {16(17)-14=258}

\displaystyle {272+-14=258}

\displaystyle {258=258}

All of these values were correct for our equation; thus, this table is our correct answer.

Example Question #86 : Understand Independent And Dependent Variables: Ccss.Math.Content.6.Ee.C.9

Select the table of values that represent the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle 8 m + 2 = n

Possible Answers:

Correct answer:

Explanation:

In the equation \displaystyle 8 m + 2 = n\displaystyle {m} is the independent variable and \displaystyle {m} is the dependent variable. This means, as we manipulate \displaystyle {m}\displaystyle {n} will change.

Because we are given tables in our answer choices, we can plug in the given value for \displaystyle {m} from the table and use our equation from the question to see if that equals the value given for \displaystyle {n} in the table.

Let's start by testing values from the following table:

\displaystyle {8(5)+2=43}

\displaystyle {40+2=43}

\displaystyle {42\neq 43}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {8 m + 2 = n} ; thus, this answer choice is not correct and can be eliminated.

Next, let's test values from the following table:

\displaystyle {8(0)+2=2}

\displaystyle {0+2=2}

\displaystyle {2=2}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {8(5)+2=84}

\displaystyle {40+2=84}

\displaystyle {42\neq 84}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {8 m + 2 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {8(4)+2=34}

\displaystyle {32+2=34}

\displaystyle {34=34}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {8(8)+2=66}

\displaystyle {64+2=66}

\displaystyle {66=66}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {8(16)+2=141}

\displaystyle {128+2=141}

\displaystyle {130\neq 141}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {8 m + 2 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {8(4)+2=34}

\displaystyle {32+2=34}

\displaystyle {34=34}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {8(6)+2=50}

\displaystyle {48+2=50}

\displaystyle {50=50}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {8(16)+2=130}

\displaystyle {128+2=130}

\displaystyle {130=130}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {8(17)+2=138}

\displaystyle {136+2=138}

\displaystyle {138=138}

All of these values were correct for our equation; thus, this table is our correct answer.

Example Question #82 : Understand Independent And Dependent Variables: Ccss.Math.Content.6.Ee.C.9

Select the table of values that represent the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle - 3 m - 9 = n

Possible Answers:

Correct answer:

Explanation:

In the equation \displaystyle - 3 m - 9 = n\displaystyle {m} is the independent variable and \displaystyle {m} is the dependent variable. This means, as we manipulate \displaystyle {m}\displaystyle {n} will change.

Because we are given tables in our answer choices, we can plug in the given value for \displaystyle {m} from the table and use our equation from the question to see if that equals the value given for \displaystyle {n} in the table.

Let's start by testing values from the following table:

\displaystyle {-3(3)+-9=-17}

\displaystyle {-9+-9=-17}

\displaystyle {-18\neq -17}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {- 3 m - 9 = n} ; thus, this answer choice is not correct and can be eliminated.

Next, let's test values from the following table:

\displaystyle {-3(4)-9=-21}

\displaystyle {-12-9=-21}

\displaystyle {-21=-21}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-3(8)-9=-66}

\displaystyle {-24-9=-66}

\displaystyle {-33\neq -66}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {- 3 m - 9 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {-3(8)-9=-33}

\displaystyle {-24-9=-33}

\displaystyle {-33=-33}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-3(10)-9=-39}

\displaystyle {-30-9=-39}

\displaystyle {-39=-39}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-3(15)-9=-43}

\displaystyle {-45-9=-43}

\displaystyle {-54\neq -43}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {- 3 m - 9 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {-3(4)-9=-21}

\displaystyle {-12-9=-21}

\displaystyle {-21=-21}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-3(9)-9=-36}

\displaystyle {-27-9=-36}

\displaystyle {-36=-36}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-3(18)-9=-63}

\displaystyle {-54-9=-63}

\displaystyle {-63=-63}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-3(19)-9=-66}

\displaystyle {-57+-9=-66}

\displaystyle {-66=-66}

All of these values were correct for our equation; thus, this table is our correct answer.

\displaystyle {13(10)-19=222}

\displaystyle {130-19=222}

\displaystyle {111\neq 222}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {13 m - 19 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {13(3)-19=20}

\displaystyle {39-19=20}

\displaystyle {20=20}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {13(8)-19=85}

\displaystyle {104-19=85}

\displaystyle {85=85}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {13(10)-19=122}

\displaystyle {130-19=122}

\displaystyle {111\neq 122}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {13 m - 19 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {13(15)-19=176}

\displaystyle {195-19=176}

\displaystyle {176=176}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {13(17)-19=202}

\displaystyle {221-19=202}

\displaystyle {202=202}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {13(18)-19=215}

\displaystyle {234+-19=215}

\displaystyle {215=215}

All of these values were correct for our equation; thus, this table is our correct answer.

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {15 m - 19 = n} ; thus, this answer choice is not correct and can be eliminated.

Next, let's test values from the following table:

\displaystyle {15(2)-19=11}

\displaystyle {30-19=11}

\displaystyle {11=11}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {15(7)-19=172}

\displaystyle {105-19=172}

\displaystyle {86\neq 172}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {15 m - 19 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {15(0)-19=-19}

\displaystyle {0-19=-19}

\displaystyle {-19=-19}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {15(5)-19=56}

\displaystyle {75-19=56}

\displaystyle {56=56}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {15(13)-19=187}

\displaystyle {195-19=187}

\displaystyle {176\neq 187}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {15 m - 19 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {15(2)-19=11}

\displaystyle {30-19=11}

\displaystyle {11=11}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {15(6)-19=71}

\displaystyle {90-19=71}

\displaystyle {71=71}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {15(7)-19=86}

\displaystyle {105-19=86}

\displaystyle {86=86}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {15(12)-19=161}

\displaystyle {180+-19=161}

\displaystyle {161=161}

All of these values were correct for our equation; thus, this table is our correct answer.

Example Question #91 : Understand Independent And Dependent Variables: Ccss.Math.Content.6.Ee.C.9

Select the table of values that represent the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle 10 m + 7 = n

Possible Answers:

Correct answer:

Explanation:

In the equation \displaystyle 10 m + 7 = n\displaystyle {m} is the independent variable and \displaystyle {m} is the dependent variable. This means, as we manipulate \displaystyle {m}\displaystyle {n} will change.

Because we are given tables in our answer choices, we can plug in the given value for \displaystyle {m} from the table and use our equation from the question to see if that equals the value given for \displaystyle {n} in the table.

Let's start by testing values from the following table:

\displaystyle {10(3)+7=38}

\displaystyle {30+7=38}

\displaystyle {37\neq 38}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {10 m + 7 = n} ; thus, this answer choice is not correct and can be eliminated.

Next, let's test values from the following table:

\displaystyle {10(9)+7=97}

\displaystyle {90+7=97}

\displaystyle {97=97}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {10(16)+7=334}

\displaystyle {160+7=334}

\displaystyle {167\neq 334}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {10 m + 7 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {10(10)+7=107}

\displaystyle {100+7=107}

\displaystyle {107=107}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {10(17)+7=177}

\displaystyle {170+7=177}

\displaystyle {177=177}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {10(18)+7=198}

\displaystyle {180+7=198}

\displaystyle {187\neq 198}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {10 m + 7 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {10(2)+7=27}

\displaystyle {20+7=27}

\displaystyle {27=27}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {10(8)+7=87}

\displaystyle {80+7=87}

\displaystyle {87=87}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {10(12)+7=127}

\displaystyle {120+7=127}

\displaystyle {127=127}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {10(15)+7=157}

\displaystyle {150+7=157}

\displaystyle {157=157}

All of these values were correct for our equation; thus, this table is our correct answer.

Example Question #1143 : Grade 6

Select the table of values that represent the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle - 16 m - 17 = n

Possible Answers:

Correct answer:

Explanation:

In the equation \displaystyle - 16 m - 17 = n\displaystyle {m} is the independent variable and \displaystyle {m} is the dependent variable. This means, as we manipulate \displaystyle {m}\displaystyle {n} will change.

Because we are given tables in our answer choices, we can plug in the given value for \displaystyle {m} from the table and use our equation from the question to see if that equals the value given for \displaystyle {n} in the table.

Let's start by testing values from the following table:

\displaystyle {-16(5)+-17=-96}

\displaystyle {-80+-17=-96}

\displaystyle {-97\neq -96}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {- 16 m - 17 = n} ; thus, this answer choice is not correct and can be eliminated.

Next, let's test values from the following table:

\displaystyle {-16(5)-17=-97}

\displaystyle {-80-17=-97}

\displaystyle {-97=-97}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-16(13)-17=-450}

\displaystyle {-208-17=-450}

\displaystyle {-225\neq -450}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {- 16 m - 17 = n} ; thus, this answer choice is not correct and can be eliminated.

\displaystyle {-16(8)-17=-145}

\displaystyle {-128-17=-145}

\displaystyle {-145=-145}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-16(11)-17=-193}

\displaystyle {-176-17=-193}

\displaystyle {-193=-193}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-16(17)-17=-278}

\displaystyle {-272-17=-278}

\displaystyle {-289\neq -278}

Because this equation did not work out, this means that not all of the values from the table are representative of the relationship between \displaystyle {m} and \displaystyle {n} if \displaystyle {- 16 m - 17 = n} ; thus, this answer choice is not correct and can be eliminated.

Finally, let's test values from the following table:

\displaystyle {-16(2)-17=-49}

\displaystyle {-32-17=-49}

\displaystyle {-49=-49}

These values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-16(8)-17=-145}

\displaystyle {-128-17=-145}

\displaystyle {-145=-145}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-16(15)-17=-257}

\displaystyle {-240-17=-257}

\displaystyle {-257=-257}

Again, these values are correct for our equation, but to be safe we should plug each value into our equation until we find a value that is not correct, or that each value is correct.

\displaystyle {-16(16)-17=-273}

\displaystyle {-256+-17=-273}

\displaystyle {-273=-273}

All of these values were correct for our equation; thus, this table is our correct answer.
