Answer: $130</h3>
=======================================================
Explanation:
I'm assuming the bank is using simple interest (instead of compound interest).
If so, then,
i = P*r*t
i = 8000*0.0325*0.5
i = 130
The amount of interest is $130
In the formula above, I used
- P = 8000 = amount deposited
- r = 0.0325 = annual interest rate in decimal form
- t = 6/12 = 0.5 years, which means you don't use t = 6. We don't use t = 6 because the interest rate is on an annual basis, and not a 6-month basis.
The variable a cannot be zero because that would make -9a = zero and 8 divided by zero is indeterminate.
Step-by-step explanation:
f(x) = 3x - 4
g(x) = -2x + 7
= (fog)(2)
= 3(-2x + 7) - 4
= 3(-2.2 + 7) - 4
= 3(-4 + 7) - 4
= 3(3) - 4
= 9 - 4
= 5
(fog)(x) = 5
