Question 1036795: On a road in the city of Madison, the maximum speed is 45 miles per hour and the minimum speed is 35 miles per hour. Let x represents the speed. You can write two inequalities to represent the speed restrictions.
maximum speed is 45 mph (x≤45) minimum speed is 35 mph (x≥35)
The inequalities x≤45 and x≥35 can be combined and can be written without using and.
35≤x≤45
a. Explain how compound inequalities can be use to describe the speed restrictions on roads.

b. Include a compound inequality describing a possible age restriction for driving on roads. Describe what this represents. (Minimum driving age is 16 years, and most drivers stop renewing their licenses by age 100.)
