Answer:
C
Step-by-step explanation:
The x- intercept is where the line crosses the x- axis. At this point on the x- axis the y- coordinate is zero.
To find the x- intercept let y = 0 in the equation and solve for x, that is
5x - 2 = 0 ( add 2 to both sides )
5x = 2 ( divide both sides by 5 )
x = 
← x- intercept
coordinates of x- intercept are (, 0 ) → C
F2=(x-4)(x+4) = 0
the x-intercepts at (4,0) and (−4,0)
The value of the building would be $699,400 in 4 years.
<h3>What will be the value of the building?</h3>
Depreciation is the when the value of an asset reduces as a result of wear and tear. Straight line depreciation is a method used in depreciating the value of an asset linearly with the passage of time.
The equation that can be used to determine the value of the building with a straight line depreciation is:
Value of the asset = initial value of the asset - (number of months x deprecation rate)
y = 829,000 - 2700x
The first step is to determine the number of months it would take for the building to have a value of $699,400.
$699,400 = 829,000 - 2700x
829,000 - 699,400 = 2,700x
129,600 = 2,700x
x = 129,600 / 2,700
x = 48 months
Now convert, months to years
1 year = 12 months
48 / 12 = 4 years

Answer:
x=-3,x=9
Step-by-step explanation:
x^2-6x-20-7=0
x^2-6x-27=0
x^2-(9-3)x-27=0
x^2-9x+3x-27=0
x(x-9)+3(x-9)=0
(x+3)(x-9)=0
x=-3,x=9
