Dilation D was performed on a rectangle. How does the image relate to the pre-image? Select three options. Vies
The image is a reduction because 0 The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.
The angles of the image are two-fifths the size of the angles of the pre-image.
The center of dilation is at point Q.
The base of the image is two-fifths the size of the base of the pre-image.

A,B and E

Step-by-step explanation:

Dilation =  was done on a rectangle.

→As Factor of Dilation is 0.4, which is less than 1.

→So, the image will be smaller in size than Pre image.

→As, the two rectangles , Pre image and image are similar so their sides will be proportional.

As in similar figures the interior angles are congruent.

As the images are similar , so Base of the image will be two fifths of the size of the base of preimage.

Option A,B and E are Correct.

A: The image is a reduction because n < 1.

B : The side lengths of the image are two-fifths the size of the corresponding side lengths of the pre-image.

E. The base of the image is two-fifths the size of the base of the pre-image.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

x=6 and x=3
