Question

HELP PLEASE :/
A transformation of a figure by a dilation with a scale factor of –2 has which characteristic?
Select one:
a. Symmetry across a line of reflection.
b. Congruent to the original figure.
c. Twice as large in every dimension, and on the opposite side of the center of dilation.
d. Side lengths that are 2 less than the original figure.

Answer 1

I honestly have no idea but I'd probably go with B

Answer 2

ive been stuck on this one for awhile

Answer 3

i see that... i tried searching it and found that u asked it on peeranswer also XD lol

Answer 4

Please show YOUR work on ALL problems submitted. No one wants to do your homework for you.
A Scale factors doesn't have a line of reflection.
B Since the Scale Factor is neither +1 or -1, it is unlikely there will be congruence.
C Hmm...
D "2 less"? I don't even understand that. What if the side length was only 1.5?!

Next time, give YOUR thoughts and show YOUR work.

Answer 5

Yeah lol no one can help me understand this one

Answer 6

wait its not B

Answer 7

or C

Answer 8

Read my four responses. Consider the merits of each. Slowly, carefully. Think them through.

Answer 9

* Scale Factors don't have a Line of Reflection.

Answer 10

I say C

Answer 11

Since a dilation stretches or shrinks the original figure and the scale factor is -2 the side lengths would be 2 less than the original figure

Answer 12

Why do you say "C"? Must learn to communicate - like someone just did!

Answer 13

Yay im smart :3

Answer 14

I say C

Answer 15

its D though...

Answer 16

Answer 17

Answer 18

It's not D, but I have no problem believing your electronic answer key thinks it's D. Sometimes they are just wrong. If you pick C and get it wrong, please complain to your teacher or grader.
