Answer:

A,C,E

Explanation:

Please trust me! You have to reduce everything by 1/4 AKA just take 25% of each OG number for example. W = -8, 8 then, applying 1/4 you'd get W = -2, 2. Then, you can do that with the rest of the numbers!

Hope this helped also ILY make sure to take a break <3

Answer:

See Explanation

Explanation:

Given


k = (1)/(4) --- scale factor

Required

Determine possible new vertices

The vertices of
\triangle UVW is not given. So, I will answer the question based on an assumed vertex for
\triangle UVW

Given that the scale factor is 1/4, the relationship between
\triangle UVW and
\triangle U'V'W' is:


U' = U * (1)/(4)


V' = V * (1)/(4)


W' = W * (1)/(4)

Assumptions:


U = (-4,-8)


V = (-4,-4)


W = (-8,-8)

So, the possible vertices are:


U' = U * (1)/(4)


U' = (-4,-8) * (1)/(4)


U' = (-1,-2)


V' = V * (1)/(4)


V' = (-4,-4)* (1)/(4)


V' = (-1,-1)


W' = W * (1)/(4)


W' = (-8,-8)* (1)/(4)


W' = (-2,-2)
