Question

solve the inequality and graph the solution. 3 + 3s > 15 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: Subtract 3 from both sides

$3 + 3s - 3 > 15 - 3$
$3s > 12$

Step2: Divide by 3 on both sides

$\frac{3s}{3} > \frac{12}{3}$
$s > 4$

Step3: Graph the solution

• Place an open circle at 4 (since the inequality is $>$, not $\geq$), then draw an arrow pointing to the right to represent all values greater than 4.

Answer:

$s > 4$
Graph: Open circle at 4, arrow pointing right.
