Question

The vertices of a figure are given. Find the coordinates of the figure after the transformations given. A(−5,3),B(−2,3),C(−2,1),D(−5,1)Reflect in the y-axis. Then dilate with respect to the origin using a scale factor of 2. (help please))!!!

Answer 1

Answer:

Reflection: A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

Dialation: A"(10, 6)

                B" (4, 6)

                C" (4, 2)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)

                D" (10, 2)          

Hoep this helps!!

Answer 2

Answer:

A"(10, 6)

               B" (4, 6)

               C" (4, 2)

               D" (10, 2)          

Step-by-step explanation:

you times everything by 2 and take away negatives symbols
