8-39.
  1. 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 ≤ 10. Homework Help ✎

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

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

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.

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