I think that the answers is b
Answer:
Option B
Step-by-step explanation:
Average rate of change of a function 'f' in the interval x = a and x = b is given by,
Average rate of change of change = 
Given function is,
g(x) = 
We have to calculate the rate of change in the interval [-4, 3],
Average rate of change = 
g(3) = 
= 2.5 + 1
= 3.5
g(-4) = 
= -1 + 1
= 0
Average rate of change = 
= 
= 
Therefore, Option B will be the answer.
Answer:
10x + 30 = 600
Step-by-step explanation:
Johnny gets $10 per week, which is $10x for x number of weeks.
He already has $30, so his money becomes 10x + 30.
His goal is to have $600, so our equation becomes 10x + 30 = 600
Both A and C are acceptable answers, because they will make either .8xoriginal servings or .2xoriginal servings.
