Boris does a weekly exercise program consisting of cardiovascular work and weight training. Each week, he exercises for at least 7 hours. He spends at most 5 hours on weight training. He spends at most 10 hours doing cardiovascular work. Let x denote the time (in hours) that Boris spends doing cardiovascular work. Let y denote the time (in hours) that he spends on weight training. Shade the region corresponding to all values of x and y that satisfy these requirements.

the answer is here: : )

:

its adding 5.5 each time

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
