A quadrilateral with vertices at (4,-4). B(4,-16) C(12,-16) and D(12,4) has been dilated with a center at the origin. The image of D, point D' has coordinates of (36,-12). What is the scale factor of the dilation?

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

can you put the picture up?

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
