Question

See attachment.

Answer 1

I have to find the new vertices using the matrix and the given "k."

Answer 2

Dilation?

Answer 3

Yes! :)

Answer 4

Do you use the Jurgesen Geometry book? I sent you a chat note last night.

Answer 5

I sent back, saying no

Answer 6

Ah thank you so much for helping me!

Answer 7

Dilations are like similarity of triangles so whatever figure we get should be similar to the original one.

Answer 8

I know for l, it would be (1, 1/3)

Answer 9

I (1, 1/3)

G (5/3, 7/3)

H (3,1)

What do you think?

Answer 10

Yup, that's what I got by mulitplying 1/3

Answer 11

Alrighty.

Answer 12

I will have more questions coming up after I finish up the similar dilation problems.

Answer 13

I think your coordinates of points P and Q may have been read wrong from the graph. Or, I can't read. :)

Answer 14

Oh, I double checked, they're right

Answer 15

I get P to be (-1, -1) and Q to be (-4, 2)

Answer 16

OHH. oops! careless mistake -.-

Answer 17

R is above P - they have to have the same x-coordinate.

Answer 18

Okay, NOW I see all my mistakes haha

Answer 19

?

Answer 20

I just messed up using a -5/2 factor.

-5/2 , -5/2 P

-10 , 5 Q

-5/2 10 R

5 , 5/2 S

Answer 21

Could you put the next attachment in a new thread? :)

Answer 22

First, let's finish this attachment. What did you get for the coordinates.

Answer 23

I got the same answers, and will do!

Answer 24

What happened??

Answer 25

Are they trolling/spamming?

Answer 26

Not at the moment. Let's work Geometry in the new thread. I'll meet you there.

Answer 27

After I work on the problems I get. I'll post some when I run into something I'm stuck on

Answer 28

Okay.
