<span>I believe this question is referring to purchasing a discount on a loan's interest rate by putting more towards closing costs. For mortgages, sometimes they will allow you to "buy" a smaller interest rate. For example:
Loan A has an interest rate of 4.5% and no closing costs.
Loan B has an interest rate of 4.375%, but has $1000 in closing costs.
Normally, Loan A would be the better choice if you plan on keeping the home short term, but Loan B would be more beneficial for keeping the loan long-term. I don't really care to spend the time that is necessary to come up with an actual scenario, but I hope that helps enough for you to understand the question</span>
The width is 6
length x width = area
8 x ? = 48
48/8= 6
You need to foil it out. That's how you get the answer.
(x+4)^20
=
(x+4) x (x+4)^19
=
(x+4)^2 x (x+4)^18
etc.
Answer:
f-1(x) = (x + 6)/7.
Step-by-step explanation:
Let f)x) = y then
7x - 6 = y
7x = y + 6
x = (y + 6)/7
Replacing the y by x and the x by the inverse f-1(x):
f-1(x) = (x + 6)/7.
