Answer:
(A) dependent variable
(B) Dependent variable
(C) independent variable
(D) independent variable
Step-by-step explanation:
F(x) is equivalent to y, so the first two equations are saying y+3 and y-3
The last two equations are saying y=x+3 and y=x-3
The equation is for when you compound annually is
A=future amount
P=initial amount or principal
r=interest rate in decimal form
t=time in years
so
A=A
P=3500
r=7.5%=0.075
t=13
use your calculator
A=8961.4457
round to nearest dollar
A=$8961
that's how much the investment will be worth after 13 years
0.000000714 is the decimal version, but as a fraction its 5/7,000,000
The answer is 20.25. I used the butterfly method to find the answer.
