Answer:
The algebraic expression for the original APR is A% + y×B/(Initial Loan Amount)
Step-by-step explanation:
Mortgage points are charges paid to the lender directly to obtain a lower interest rate amount for a loan borrowed. Basically, it entails up front payment of interest that allows for a determination of a new reduced interest rate.
Here we have new APR = A%
Original APR = O%
% reduction of APR per point = y%
Cost of points = B dollars
Therefore, the original APR was A% + y×B/(Loan Amount)
Hence the algebraic expression for the original APR is therefore;
Original APR = A% + y×B/(Loan Amount).
Answer:
k = -7
Step-by-step explanation:
Given
x² - x - 42 = (x + k)(x + 6)
Required
Find k
x² - x - 42 = (x + k)(x + 6)
Expand the left hand side
x²-7x + 6x - 42 = (x + k)(x+ 6)
Factorize
x(x - 7) + 6(x- 7) = (x + k)(x+ 6)
Further factorize
(x - 7)(x + 6) = (x + k)(x + 6)
By comparison
x + k = x - 7
Subtract x from both sides
k = -7
