Example Question #1 : Simplifying Inequalities
Consider the inequality
Which of the following statements has the same solution set?
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 #1 : Simplifying Inequalities
Consider the inequality
Which of the following statements has the same solution set?
is equivalent to the three-way inequality
Add 7 to all three expressions to yield the statement:
This is the correct response.
Example Question #1 : Simplifying Inequalities
Which coordinate is a solution to the inequality
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 #2 : Simplifying Inequalities
Simplify the following inequality:
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
