Question

solve the inequality and graph the solution. 73 + 18r ≥ 37 plot the endpoints. select an endpoint to change middle of the segment, ray, or line to delete it.

Explanation:

Step1: Subtract 73 from both sides

$73 + 18r-73\geq37 - 73$
$18r\geq - 36$

Step2: Divide both sides by 18

$\frac{18r}{18}\geq\frac{-36}{18}$
$r\geq - 2$

To graph, we plot a closed - circle at $r=-2$ (because the inequality is $\geq$) and draw a ray to the right.

Answer:

$r\geq - 2$; On the number - line, plot a closed - circle at $-2$ and draw a ray to the right.
