Mia bought a used car for $9,500. It is expected that the value of the car will decrease by an average of $750 each year. Which function can be used to find the
value of the car in x years after Mia purchased it?
A. f(x)=95000-750x
B. f(x)=95000+750x
C. f(x)=-750(x+9500)
D. f(x)=-9500(x-750)

I believe the answer is D

Step-by-step explanation:

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
