Question

solve the inequality and graph the solution. 9s < 27 to draw a ray, plot an endpoint and select an arrow. select an endpoint to change it from closed to open. select the middle of the ray to delete it.

Explanation:

Step1: Isolate the variable s

Divide both sides of $9s < 27$ by 9. So, $\frac{9s}{9}<\frac{27}{9}$.

Step2: Simplify the inequality

We get $s < 3$.

Answer:

The solution of the inequality is $s < 3$. On the number - line, we plot an open circle at 3 (since 3 is not included in the solution) and draw an arrow to the left.
