Question

solve the inequality and graph the solution.
-31 ≤ h - 28
plot the endpoints. select an endpoint to change it from closed to open. select the middle of the segment, ray, or line to delete it.

Explanation:

Step1: Add 28 to both sides

$-31 + 28\leq h-28 + 28$

Step2: Simplify the expressions

$-3\leq h$ or $h\geq - 3$

Answer:

The solution of the inequality is $h\geq - 3$. On the number - line, we plot a closed circle at $-3$ (since the inequality is $\geq$) and draw a ray to the right.
