9-54.

Solve each inequality below algebraically. Then represent your solution on a number line.

$5x-7\ge2x+5$
Partial Answer (a):
$x ≥ 4$

$6x-29>4x+12$

$x^2\le-4x+5$
Step 1(c):
$x^2=-4x+5$
Step 2(c):
$x^2+4x-5=0$
Step 3(c):
Factor and use the Zero Product Property to solve for the boundary points. Place the boundary points on a number line then test a point in each region to determine which regions contain the solutions.
