Answer:

<em>f(a - 4) = 3a - 10</em>

Step-by-step explanation:

As given, we have here, an original equation: f(x) = 3x + 2.

To work out f(a - 4), we substitute x = a - 4 into original equation.

f(a - 4) = 3(a - 4) + 2

We apply the distributive property to keep going.

f(a - 4) = 3a - 3*4 + 2

We perform the multiplication of 3 and 4.

f(a - 4) = 3a - 12 + 2

We perform the addition of (-12) and 2 to finalize the answer.

f(a - 4) = 3a - 10

This is the final answer

I hope this helps!

You get a student loan from the New Mexico Educational Assistance Foundation to pay for your educational expenses this year. Fin
KIM [24]

Answer:

$554.58

Step-by-step explanation:

The interest on the loan can be computed by first determining the future value of the loan in three years as follows:

FV=PV*(1+r)^n

PV is the amount of the loan which is $2,000

r is the interest rate which is 8.5%

n is the number of years which is 3 years

FV=$2000*(1+8.5%)^3=$ 2,554.58  

Since the value of the loan in three years is $ 2,554.58 ,the interest on the loan is the difference between the future value and the present value

interest=$ 2,554.58-$2,000.00=$554.58
