Answer:
603
Step-by-step explanation:
The rate of change is found by
rate of change = f(b) -f(a)
------------
b-a
We need to find the rate of change for the interval 7,9 and 4,6
We know b= 9 and a = 7
f(9) -f(7)
------------
9-7
3878-1852

We know b= 6 and a = 4
f(6) -f(4)

It asks how much greater, that means subtraction

Y = x² + 2x – 45
y = -3x + 5
-3x + 5 = x² + 2x – 45
x² + 5x – 50 = 0
x has two values 5 and -10
x = 5 => y = -10
x = -10 => y = 35
Good luck.
In order to do this, we multiply both sides be the amount that would make the left side equal to 1. This number is the reciprocal of the fraction, so we multiply both sides by 3/2. This is equal to:
w = 9/8
So, the blueberries in crystal's basket will weigh 9/8 pounds when it is full.
Your welcome!
If I'm correct, this polynomial factored would just be c(8c+7)
