3x
2
c. Solve the equation
x - 4
x² – 16
using LCD
d. Compare the methods used to solve the equation in parts cand d. Which
method do you think is better and why?
x + 4

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.

just sum

10 + 10 = 20
