Question

HELP PLEASE

Answer 1

Two similar triangles are shown on the coordinate grid:

A coordinate grid is shown from positive 6 to negative 6 on the x-axis and from positive 6 to negative 6 on the y-axis. A triangle MNO is shown with vertex M on ordered pair negative 2, 4, vertex N on ordered pair 0, 0, and vertex O on ordered pair negative 6, negative 2. A triangle M prime N prime O prime is also shown with vertex M prime on ordered pair 1, 2, vertex N prime on ordered pair 0, 0, and vertex O prime on ordered pair 3, negative 1.

Which set of transformations has been performed on triangle MNO to form triangle M'N'O'?

Dilation by a scale factor of 2 followed by reflection about the x-axis
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the x-axis
Dilation by a scale factor of 2 followed by reflection about the y-axis
Dilation by a scale factor of fraction 1 over 2 followed by reflection about the y-axis

Answer 2

any diagram?

Answer 3

reflection is a mirror.

the new triangle is 2 times bigger than old one.

what do you think the answer is?

Answer 4

OK I THINK ITS A OR C

Answer 5

iM thinking

Answer 6

you are correct, it is C

Answer 7

so look: each side of the new triangle is 2 times bigger than sides of old one thus the dilation factor is 2.

then you reflect it across y asis.

Answer 8

oh ok ok
