Please help! Solve the following:
mihalych1998 [28]

Answer:

n=10.

Step-by-step explanation:

\frac{45}{n^{2}-3n-4 } - \frac{3}{n-4} = \frac{2}{n+1 }

\frac{45}{n^{2}-3n-4 } -  \frac{3(n+1)}{(n+1)(n-4)} = \frac{2(n-4)}{(n+1)(n-4) }

\frac{45}{n^{2}-3n-4 } -  \frac{3n+3}{n^{2} -3x-4} = \frac{2n-8}{n^{2} -3x-4 }

45-3n-3=2n-8

45-3+8=5n

n=50/5=10

Mike has a credit rating of 720. Tyler has a credit rating of 560. Mike and Tyler apply for identical loans from Park Bank. Mike
Eva8 [605]

Answer:

6.2%

Step-by-step explanation:

Credit rating is an evaluation of the credit risk of a borrower, that how often a person is going to repay their debt, by credit rating it predicts the ability of the debtor to payback.

Mike has credit rating = 720

Tyler has credit rating = 560

Both are approved for loan. Mike's Credit score is higher, which means he is a much safer debtor as compared to Tyler. Mike will be able to pay back much easily than Tyler. Therefore Mike interest rate is 3.2%

Interest rate of Tyler is higher as he is not that trusted and has low Credit rating. Tyler is approved for a loan that charged 3 percentage points higher because of his inferior credit rating so it interest on the loan will be

Interest = 3.2%+3% = 6.2%
