Sam went to an amusement park. From the main entrance he used the algebraic representation (x, y)—>(x - 10, y + 14) to walk to a ride. Which ride did Sam walk to? (8.10c)

4x and 6y

im not sure though

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)

the answer is 40.

proof:
