8-39.

The recommended speed on a scenic road is $35$ mph. Driving too fast is a hazard, but so is driving too slowly. Safe speeds s may be described by the inequality $|35-s|$≤ 10.

1. Find a list of at least $5$ safe speeds.

What values can you substitute for s that would make this inequality true? Remember, there can be many different answers.

One possible answer is $25$ mph.

2. Determine how to show the entire set of possible values (solutions) for s by graphing them on a number line.

Use your list from part (a). You will need to determine the fastest and the slowest safe speeds.
