Answer:
Slope = -2/2 = -1
x-intercept = 6/1 = 6
y-intercept = 6/1 = 6
I wasn't sure what you really were asking for, so I did slope, x, and y.
79 / 10 = 7.9
Hope that helps...
Times both sides by -1
-8x=x²-20
add 8x both sides
0=x²+8x-20
factor
what 2 numbers multiply to get -20 and add to get 8
-2 and 10
0=(x-2)(x+10)
set to zero
x-2=0
x=2
x+10=0
x=-10
x intercepts at x=-10 and 2 or at the points
(-10,0) and (2,0)
Answer:
$809.32
Step-by-step explanation:
The loan amount is 80% of $150,000, or $120,000. The monthly payment of principal and interest is $586.82.
The total annual expense for taxes and insurance is $1920 +750 = $2670, so the monthly expense is $2670/12 = $222.50.
Then the total of payments for mortgage and escrow will be ...
$586.82 +222.50 = $809.32
__
The monthly P&I payment is given by ...
A = P(i/12)/(1 -(1 +i/12)^(-12t)) . . . . . where i is the annual interest rate, t is the number of years, and P is the amount financed.
A = $120,000(0.042/12)/(1 -(1 +0.042/12)^(-12·30)) ≈ $586.82
__
A spreadsheet or financial calculator can be useful for calculating payments, though the formula isn't difficult to use.
It is a binomial. Two terms: 3x, 1
