Answer:
4(x-2) isn't equal to the others because when simplified it is 4x-8
Step-by-step explanation:
D 1/15

Answer:
B) It decreases 22% per year.
Step-by-step explanation:
We are given that The value, v(.r), of his portfolio can be modeled with the function : 
Where x is the number of years since he made his investment.
Formula :
Where P = Principal
r = rate of decrease
t = time
A = Amount after t years
So, On comparing
P = 30000
t=x
A=y(x)



So, r = 0.22
r=22%
So, Rate of decrease is 22%
So, Option B is true,
It decreases 22% per year.
Answer:
x + 6
Step-by-step explanation:
Edit:
A moderator mentioned my answer had a mistake: turned out the question posted was incomplete. The complete question should read:
"
What must be a factor of the polynomial function f(x) graphed on the coordinate plane below?
x – 6
x – 3
x + 1
x + 6
"
As shown in the same graph, f(x) cross the x-axis at x = -6, -3 and 0.
When a polynomial crosses the x-axis at x = a, (x - a) must be a factor.
So (x + 6), (x + 3) and x are factors of f(x).
Of the options, the correct answer is x + 6.
