givi [52]

Answer:

A' (-2,8) B' (-2,-4) C' (4,-4)

Step-by-step explanation:

Dilations Rule :

(x,y) → (kx,ky)

Scale factor = K

When your scale factor is more than one our triangle gets bigger. When your scale factor is less than one our triangle gets smaller.

( you plug in 2 in every point and those are your answers).

Remember negative times negative is positive and positive times negative is negative.

I need help pls and thank you...

Answer:

AB = 32

Step-by-step explanation:

Since line l bisects AB at point M, we have AM = MB.

$4x = 5x - 4$

$4x + 4 = 5x$

$x = 4$

AM = 4(4) = 16, MB = 5(4) - 4 = 16.

So AB = AM + MB = 16 + 16 = 32.
