Answer:
$1486.41.
Step-by-step explanation:
Purchase price = $309,900
Down payment percent = 20 %
Remaining amount Percentage = 100-20 = 80%
Mortgage amount = 
=
Formula of monthly payment : 
where P = the payment,
r = the annual rate =6% = 0.06
M = the mortgage amount = $247920
t = the number of years=30
n = the number of payments per year= 12
Substitute the values.
Hence the monthly payment is $1486.41.
Thus Option C is correct.
D) y=-2x^2-x is quadratic, when graphed it will create a parabola.
Answer:
140°
Step-by-step explanation:
The value of supplement is 40 and X. We know that the sum of the sumplementary angles is 180. Therefore ,
=> x + 40° = 180°
=> x = 180° - 40°
=> x = 140°

Step-by-step explanation:
the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4
since we know the area is = 7 therefore
x^2 + 4x +4 = 7 and x^2 + 4x = 3
if you want to find the value of x :
x^2+4x+4 = 7
x^2+4x -3 = 0
(x-3)(x-1)=0
x = 3 or
x = 1
