Answer:
x = - 7, y = 6
Step-by-step explanation:
7x + 7y = - 7 -----> equation 1
- 10x - 7y = 28 -----> equation 2
Add equations 1 & 2,
7x + 7y = - 7
- 10x - 7y = 28
___________
- 3x + 0 = 21
- 3x = 21
x = 21 / - 3
x = - 7
Substitute x = - 7 in equation 1,
7x + 7y = - 7
7y + 7x = - 7
7y + 7 ( - 7 ) = - 7
7y - 49 = - 7
7y = - 7 + 49
7y = 42
y = 42 / 7
y = 6
Maybe you should work on starting you're sentences.
C(h,k) radius(r)
C(2,-3) r=4
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16
therefore, the answer is D
Answer:
A. $307,172.72
Step-by-step explanation:
Inez has to pay 4 percent in closing costs and 16 percent for the down payment on a purchase of $225,500 with an ARM.
4% + 16% = 20%
lnez has to pay 20% of $225,500
= 225,500*20/100
= 225,500*0.2
= $45100
lnez has to pay $45100.
Over the life of the loan, lnez will pay $262,072.72
Now we have to add down payment, closing cost and the payment over the life of the loan.
$45100 + $262,072.72
= $307,172.72
Answer: A. $307,172.72
Thank you.
