Question

solve the inequality and graph the solution.
r - 52 ≥ -50
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 52 to both sides

$r - 52+52\geq - 50 + 52$

Step2: Simplify the inequality

$r\geq2$

Answer:

The solution of the inequality is $r\geq2$. On the number - line, we plot a closed circle at $r = 2$ (since the inequality is $\geq$) and draw a ray to the right of 2.
