Answer 1

Answer 2

First off, do you know what dialation is?

Answer 3

Yes!

Answer 4

OK, so, they have one start and one resultant measure. When you dialate, you multiply. So, do you know how you would set that up in an equation with an unknown?

Answer 5

Not really, honestly.

Answer 6

If \(a\) dialtes to \(b\) then the basic formula is \(ax=b\). Then sove for x. Put your numbers in and do that.

Answer 7

9x=6?

Meaning x=2/3

Answer 8

Yep! Which would be the dialation.

Answer 9

Got it! Thank you so much!

Answer 10

Or scale factor.
