Noelle goes east at N mph.
Karina travels west at N + 9
then their velocity between them is (N + N + 9)
After 8 hours they travel 8(2N + 9) = 232
(2N + 9) = 29
2N = 20
N = 10 mph for Noelle
N+9=19 mph for Karina

Which transformation is not always congruent with its original image
Anika [276]

If they're asking for "congruent" which we know is the shape is the same or equal to. Out of the transformations I assume Dilation because you're altering the size of the shape meaning the image is either bigger than or less than the pre-image. Of course a shape bigger is not equal to the original shape.

think of a king size candy bar to a fun size bar. they're not congruent or the same
