Question

Given a scale factor of 23

and the coordinates of an image after a dilation using (0, 0) as the center of dilation, determine the coordinates of the pre-image. Fill in the blanks for the missing x and y values.

pre-image image
A (0, 3) A' (0, )

B (-6 , ) B' (-4, 8)

C ( 9, 0) C' ( , 0)

Answer 1

scale factor(k)=23

A(x,y)=A'(kx,ky)

Let's do by using this formula

C(9,0)=C'(kx,ky)(here x=9 and y=0)

C(9,0)=(23*9,23*0)

C(9,0)=(207,0)

A(0,3)=A'(kx,ky)(here x=0 and y=3)

A(0,3)=A'(23*0,23*3)

A(0,3)=A'(0,69)

sorry i dont know how to do B no
