Question 2 unsaved a person’s theoretical maximum heart rate (in heartbeats per minute) is 220 - x where x is the person’s age in years (20 ≤ x ≤ 65). when a person exercises, it is recommended that the person strive for a heart rate that is at least 50% of the maximum and at most 75% of the maximum. the system of linear inequalities that describes the given information is y> 120-1/2x (for 50% max heart rate) and y< 165-3/4x (for 75%). b. 40-year-old person has a heart rate of 158 heartbeats per minute when exercising. is the person’s heart rate in the target zone? explain
