Question

composition of rigid motion using dialation and enlargement

Answer 1

do you have original points?

Answer 2

First, figure out if its enlargement/shrink :
Is the image big/small compared to the preimage ?

Answer 3

the preimage is smaller than the image

Answer 4

Yes, or the image is much bigger than the preimage. so its an enlargement.
So strike off last two options.

Answer 5

ok

Answer 6

so now what

Answer 7

Look at H :(1, 1)

say after transformation, it goes to (x, y) :
T(1,1) --> (x, y)

after dilation by a factor of 2, it goes to :
D2 (x, y) --> (2, -10)

Answer 8

D2 (x, y) --> (2, -10)


2x = 2
2y = -10

solve x and y

Answer 9

you've closed that question, that means you figured out how to do this ? :)

Answer 10

yes

Answer 11

yes that was the solution
