which rule yields the dilation of the figure bcde centered at the origin?
a) (x, y) → (4x, 4y)
b) (x, y) → (1/4x,1/4y)
c) (x, y) (x+4, y+4)
d) (x, y) (x+ 1/4, y + 1/4)

Step-by-step explanation:

Quadrilateral BCDE has coordinates B(-8,4), C(0,4), D(8,8) and E(0,8).

Quadrilateral B'C'D'E' has coordinates B'(-2,1), C'(0,1), D'(2,2) and E'(0,2).

When we analyze the coordinates carefully, we realize that the coordinates of the preimage quadrilateral is multiplied by ¼ to obtain the coordinates of the image triangle.

Therefore the rule of the dilation is

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.

4+4+2x

or

2x+8
