The unknown number is 1/2 or 0.5.
ex: 4x+6=8
f(x) = 5x^2 - 4x
g(x) = 5x + 1
Therefore f - g = 5x^2 - 4x - (5x + 1)
= 5x^2 - 4x - 5x -1
= 5x^2 -9x - 1
Hope it helps :)
Answer:
1. 75
2. 1
Step-by-step explanation:
So, we are looking for F of G of 2. So, we need to work backwards and find G(x) first.

So we know that g(-2) = -6, now we take thatt -6 and plug in into f(x)

68 is the answer
916.60 will go to interest the first month.
The monthly interest rate is found by calculating
(5.5/100)/12 = 0.004583
Multiplying this by the amount of principal, we have
200000*0.004583 = 916.60
