Example Question #1 : Simplifying Inequalities

Consider the inequality

 

Which of the following statements has the same solution set?

Possible Answers:

Correct answer:

Explanation:

can be written as the compound inequality statement

In each expression, 9 can be subtracted to yield the inequality statement

This is the correct response.

Example Question #2 : Simplifying Inequalities

Consider the inequality

 

Which of the following statements has the same solution set?

Possible Answers:

Correct answer:

Explanation:

is equivalent to the three-way inequality

This is the correct response.

Example Question #1 : Simplifying Inequalities

Which coordinate is a solution to the inequality

 

Possible Answers:

Correct answer:

Explanation:

Subtract 1 on both sides of the inequality to get

From here we plug in each set of coordinates to see which could satisfy the statement.

This is a true statement therefore we say that (0,2) satisfies the inequality.

 

Example Question #2063 : Algebra Ii

Simplify the following inequality:

Possible Answers:

Correct answer:

Explanation:

To simplify an inequality we want to isolate the variable on one side of the inequality sign. In order to accomplish this remember to do the reverse opperation to move numbers from one side to the other.

The reverse operation of subtraction is addition. Therefore to move the three from the left hand side to the right hand side we will need to add 3 on each side of the inequality to get

.

From here divide each side of the inequality by 3 to isolate the variable, and since 3>0 we get
