It is a supplementary angle. D because the add up to 180.
Step-by-step explanation:
x intercept is when y = 0 and y intercept is when x = 0 hence, x intercept is : x = -56 hence (-56, 0) and y intercept is: 4y = -56 y = -14 hence (0, -14)

Answer:
The value of x is:
Step-by-step explanation:
we have to use the quadratic formula to solve for x.
The equation is given as:
which could also be written as:
The quadratic formula for the quadratic equation of the type:
is given as:
Here we have:
a=4, b=-5 and c=8.
Hence, by the quadratic formula we have:
Hence, the value of x is:
<span>(2) y is the total cost, x is the number of months of service, $40 is the installation fee, and $90 is the service charge per month.</span>
y = 40 + 90x
y = total cost
x = number of months of service
40 = one time installation fee
90 = monthly service charge.
Let us assume that the number of months of service is 10 months. then, the total cost would be:
y = 40 + 90(10)
y = 40 + 900
y = 940
