Problema Solution

During a workout, Vince tries to keep his heart rate at 134 beats per minute. His actual heart rate varies from this value by as much as 8 beats per minute. Write and solve an absolute-value inequality to find Vince's range of heart rates.

Answer provided by our tutors

let 'x' represents Vince's heart rate


His actual heart rate varies from 134 beats per minute by as much as 8 beats per minute:


|134 - x| <= 8


by solving we find:


x <= 142


x >= 126
