Question

solve the inequality and graph the solution.
4 + 5s ≤ 19
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 4 from both sides

$$4 + 5s-4\leq19 - 4$$
$$5s\leq15$$

Step2: Divide both sides by 5

$$\frac{5s}{5}\leq\frac{15}{5}$$
$$s\leq3$$

Answer:

The solution of the inequality \(4 + 5s\leq19\) is \(s\leq3\). On the number - line, we plot a closed circle at \(s = 3\) (since the inequality is \(\leq\)) and draw a ray to the left of \(3\) (towards the negative direction).
