Answer:
m=2
Step-by-step explanation:
When you put a number into the inverse of a function (f^-1) you get the original number back.
Ex: f^-1(11) = (11-3)/2 = 4
f(4) = 2×4+3 = 11
So, f(-5)=-2
So, when x is -5,
f(x) = -2
f(x)=m(-5)+8
-2=m(-5) + 8
m=2
Answer:
76%
Step-by-step explanation:
First do 700 - 168 which is 532
Next we see that 700 is 100% in this scenario
Then we will use the value we seek as ‘x’
So, x% = 532
We can put the two equations, 100%/x% = 700/532
they both have LHS
We can take the inverse from both sides yields
Therefore, the answer is 76%
it is 3 numbers all together and they are 25, 36 and 49.

Answer:
a. $3,455.20
Step-by-step explanation:
The monthly payment is given by the amortization formula:
A = P(r/12)/(1 -(1 +r/12)^(-12t))
for loan amount P at annual rate r for t years.
For this mortgage, we use P = $530,000, r = 0.068, t = 30.
A = $530,000(0.068/12)/(1 -(1 +0.068/12)^(-360)) ≈ $3,455.20
The monthly payment is $3,455.20.
