Question

solve the inequality and graph the solution.

$\frac{s + 7}{2}geq2$

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: Multiply both sides by 2

$2\times\frac{s + 7}{2}\geq2\times2$
$ s + 7\geq4$

Step2: Subtract 7 from both sides

$s+7 - 7\geq4 - 7$
$s\geq - 3$

Answer:

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