Aperson’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%). a. graph the system. place a photo or link below to your graph.
