I’m guessing 27 4? I’m not sure
Answer:
The function, f(x) to model the value of the van can be expressed as follows;

Step-by-step explanation:
From the question, we have;
The amount at which Amrita bought the new delivery van, PV = $32,500
The annual rate of depreciation of the van, r = -12% per year
The Future Value, f(x), of the van after x years of ownership can be given according to the following formula

Therefore, the function, f(x) to model the value of the van after 'x' years of ownership can be expressed as follows;

Answer:
5
Step-by-step explanation:
You can express this as a system of equations:
x in this instance will be her present age.
x + 8 = 2x + 3
simply solve for x after this by subtracting three and x from both sides, and you’ll find that x is 5.
Answer:
28
Step-by-step explanation:
f(6) = -3 * 6 + 10 = -18 + 10 = -8
g(f(6)) = g(-8)
g(-8) =
= 64 - 24 - 12 = 64 - 36 = 28
N + d = 21
0.5n + 0.10d = 1.35
5n + 10d = 135
d = 21-n
5n + 210 - 10n = 135
-5n = -75
n = 15
d = 6
