Write a compound inequality that represents each situation. Graph your solution.
On a road in the city of Rochester, the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.
20 ≤ x ≤ 50
Here, x represents the speed in miles per hour.
This compound inequality means that the speed must be between 20 and 50 miles per hour in order to comply with the road regulations in the city of Rochester.
Graph:
---[=======(20)=====(50)=======]---
The point (20) and (50) are included in the range.
