The answer would be a bc 600/800 simplified is 3/4
So firstly, we have to find f(x) when x = 8 and x = 0. Plug the two numbers into the x variable of the function to solve for their f(x):

Now that we have their y's, we can use the slope, aka average rate of change, formula, which is
. Using what we have, we can solve it as such:

In short, the average rate of change from x = 0 to x = 8 is 5/21.
Option A, it’s the base times the height
Answer:
16/5 or 3.2
Step-by-step explanation:
4cm/5km = x/4km
Cross multiply to find answer
So you just have to use distance formula
