Yolanda does a weekly exercise program consisting of cardiovascular work and weight training. each week, she exercises for at least 10 hours. she spends at most 6 hours doing cardiovascular work. she spends at most 8 hours on weight training. let x denote the time (in hours) that yolanda spends doing cardiovascular work. let denote the time (in hours) that she spends on weight training. shade the region corresponding to all values of x and y that satisfy these requirements.

See explanation

Step-by-step explanation:

Let x denote the time (in hours) that Yolanda spends doing cardiovascular work. Let y denote the time (in hours) that she spends on weight training.

1.  Each week, she exercises for at least 10 hours. Thus,

2. She spends at most 6 hours doing cardiovascular work. So,

3. She spends at most 8 hours on weight training. Then,

Note that times x and y are always no less than 0, so
