Question

solve for s and graph the solution.
-11 ≤ s - 15 < 5
plot the endpoints. select an endpoint to change it from closed to open. select the middle of
a segment, ray, or line to delete it.
submit

Explanation:

Step1: Add 15 to all parts of the inequality

$$\begin{align*} -11 + 15&\leq s-15 + 15<5 + 15\\ 4&\leq s<20 \end{align*}$$

Answer:

The solution is \(4\leq s<20\). On the number - line, we plot a closed circle at \(s = 4\) (because the inequality includes equality for \(s = 4\)) and an open circle at \(s=20\) (because the inequality is strict for \(s = 20\)), and then connect the two points with a line segment between them.
