Answer:
(5,-6) is a solution
Step-by-step explanation:
Given


Required
Tell whether (5,-6) is a solution
In (5,-6): x = 5 and y = -6.
Substitute these values in the given equations
becomes



becomes



Because both solutions are true, then (5,-6) is a solution
Answer:
The amount of the loan is $120,000 -10% + 2% = $110,400, assuming the "points" are added to the financed amount.
I find that the monthly payment will be
$848.89. There will be 360 such payments over 30 years, for a total payment amount of $30The amount of the loan is $120,000 -10% + 2% = $110,400, assuming the "points" are added to the financed amount.
R = Pi/[1 - (1+i)^(-n)] where
P = 110,400
R = the monthly payment
i = 8.5/[100(12)] = .007083...
n = 30(12) = 360 yielding
R = $848.88 per month.
Therefore, the total interest paid is 360(848.88) - 100,400.
5,600. Subtract the original principle (110,400) from that to get the interest paid.

Answer:
The sum of the first 8 terms in the series is 65535.
Step-by-step explanation:
We have,
The common ratio in a geometric series, r = 4
First term of GP is, a = 3
It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :

Here, n = 8

So, the sum of the first 8 terms in the series is 65535.
Steps to solve:
7 = 11t
~Divide 11 to both sides
7/11 = 11t/11
~Simplfy
7/11 = t
The fraction can't be simplified any further.
Best of Luck!
2 - 7 = -5
8i - 2i = 6i
-5 + 6i is your answer
hope this helps
