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))!!!

Answers

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)

I am loosing soo much of my points by doing this I was at 102 now I am at 40 please answer these correctly

Answers

Answer:

C

Step-by-step explanation:

If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.

A 4 + 3 ≥ 1   True, it's greater, but it can't be equal to.

B 3(4) ≥ 1     It's greater once again, can't be equal to.

C 4 - 3 ≥ 1     If x can also be greater than 4, then it works both ways. Equal and greater than.

Number 8 is A. 4, when a letter/variable is right beside number you multiply it. So since n=4, the equation should be 7 x 4 + 14= 42...also keep in mind the answer has to be less than 56

So A.4
