Question

Write the absolute value inequality for the following: Do not solve.

The cruise control of a car set a 55mph should keep the speed (s) within 3 mph of 55mph.

Answer 1

|s -55| ≤ 3

Explanation:

The cruise control of a car set a 55mph should keep the speed (s) within 3 mph of 55mph.

The absolute value inequality for the given statement, without solving is

|s -55| ≤ 3/

Answer 2

|s -55| ≤ 3

Explanation:

"Within 3 mph of 55 mph" means the magnitude of the difference between s and 55 is at most 3. In symbols, this is ...

|s -55| ≤ 3
