7-69.

Evaluate the inequality, $3x-3 ≥ 2x + 3$ , for the listed values of $x$ . Decide if the value makes the statement true or false. Show your work.

Hint:

Substitute each value in for $x$ and solve the inequality to see if it is true or false.

$x =-3$
Step 1(a):
$3(-3)-3 ≥ 2(-3) + 3$
Step 2(a):
$-9-3 ≥-6 + 3$
Answer (a):
$−12 ≥ −3$
False

$x = 9$

$x = 6$

$x = 10 \frac { 1 } { 2 }$
Answer (d):
True. Be sure to know why this is the answer.
