10-7.

Solve each of the following inequalities for the given variable. Represent your solutions on a number line.

$2(3p + 1) > -4$
Step 1(a):
Solve the equation $2(3p +1) = −4$ to find the boundary point.
Step 2(a):
Test values on both sides of the boundary point ( $p = −1$ ) to determine the solution region.
More Help (a):
$2(3(−2) + 1) > −4$
$2(−5) > −4$
$−10 > −4$
False
$2(3(0) +1) > −4$
$2(1) > −4$
$2 > −4$
True
