Question

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.)

Answer 1

Step 1

Given;

`Combined\text{ inequality 35}\leq x\leq45\text{ about speed limit}`

Step 2

Explain how compound inequalities can be used to describe the speed restrictions on roads.

The compound inequality about the speed limit has two 2 limits. A lower boundary and an upper boundary. The lower speed limit is 35mph and the upper-speed limit is 45mph.

This means that a restriction was put on the speed limit on that road and you cannot be moving at a speed of fewer than 35 miles per hour and more than 45 miles per hour.

So compound inequalities can be used to let drivers know the minimum and maximum Speed allowed on roads.

Step 3

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.)

Let d represent age

`16\leq d\leq100`
