Question 2 Unsaved A person’s theoretical maximum heart rate (in heartbeats per minute) is 220 - x where x is the person’s age i
n 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

Answer:
-5
Step-by-step explanation:
For a given x value a <u><em>function</em></u> can have only one y value.
-5 cannot have both 15 and 20 as the y value
The answer is a square.
All four sides are congruent.
Answer:
y= -x+5
y=mx+b
m=slope=-1
b=y-intercept=5
