Average rate of change = slope
Use slope formula. (Rise over Run)
look at the 2 points where x=0 and x = 2, this interval covers the first 2 seconds.
f(0) = 50, f(2) = 100
The avg rate of change is 25 units per second.
Answer:
(a-b) = -25
Step-by-step explanation:
(a+b) = -5
a*b=-150
So one of the letters have to be negative as you can only get a negative product from a positive and negative
There is probably a better way to do this, but I just plug in numbers that I think will work
So, (a*b) = -150, (-15*10) = -150
Okay that works so lets try the other one
(-15+10) = -5
This also works, so lets do the third one
(-15-10) = -25
