∆ABC is transformed with the center of dilation at the origin.

jonny [76]

<u>Answer:</u>

1/5

<u>Step-by-step explanation:</u>

We are to find the scale factor of the dilation that maps the pre-image of triangle ABC with vertices A(−3, 4), B(−1, 12) and C(4, −2) to the image triangle A'B'C' with vertices A' (−0.6, 0.8), B' (−0.2, 2.4) and C' (0.8, −0.4).

Center of dilation is at the origin.

To find the scale factor, we will divide the corresponding vertices of the image and pre-image.

A (−3, 4) ---> A' (−0.6, 0.8) = $\frac{-0.6}{-3} , \frac{0.8}{4}=(\frac{1}{5} , \frac{1}{5})$

B(−1, 12) ---> B' (−0.2, 2.4) = $\frac{-0.2}{-1} , \frac{2.4}{12} = (\frac{1}{5} , \frac{1}{5})$

C(4, −2) ---> C' (0.8, −0.4) = $\frac{0.8}{4} , \frac{-0.4}{-2} = (\frac{1}{5} , \frac{1}{5})$

Therefore, the scale factor of the dilation is 1/5.

Can someone plsss help :)

OLga [1]

Set equal to eachother
(2x+1) = 79
Subtract 1 from both sides
2x=78
Divide 2 from both sides
2x/2=78/2
X= 39

Is 1/4 of 12 greater than 1/4 of 8

grin007 [14]

" of " means multiply

1/4(12) = 12/4 = 3

1/4(8) = 8/4 = 2

so 1/4 of 12 is greater then 1/4 of 8
