Match the inequality to the number line that represents its solution

Number lines                             Inequality

First                   ⇔              

Second             ⇔              

Third                 ⇔              

Fourth              ⇔              

Inequality 1.

Multiply both sides by 9 , we get

Divide both sides by 7, we get

which is shown by the fourth number line.

Inequality 2.

Multiply both sides by 4 , we get

Divide both sides by -6, we get

which is shown by the second number line.

Inequality 3.

Multiply both sides by 4 , we get

which is shown by the first number line.

Inequality 2.

Multiply both sides by 3 , we get

Divide both sides by 2, we get

which is shown by the third number line.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
