What do u need help on?....

OpenStudy (lexi724):

If parallelogram JKLM is rotated 270° clockwise around the origin, what are the coordinates of the endpoints of the side congruent to side JM in the image parallelogram? J'(-2, -6); M'(1, -5) J'(6, 2); M'(-5, 1) J'(2, 6); M'(-1, 5) J'(6, -2); M'(5, 1)

OpenStudy (lexi724):

i say c but im not confident in it

OpenStudy (lexi724):

and i have more than one question, but ill work on 1 at a time

OpenStudy (anonymous):

I think it's c too.

OpenStudy (lexi724):

thanks @RaymondoOnley will you help with another

OpenStudy (lexi724):

What set of transformations are applied to parallelogram ABCD to create A'B'C'D'?

OpenStudy (lexi724):

reflected over the x-axis and rotated 180° reflected over the y-axis and rotated 180° reflected over the x-axis and rotated 90° counterclockwise reflected over the y-axis and rotated 90° counterclockwis

OpenStudy (lexi724):

i said B

OpenStudy (anonymous):

I would say C.

OpenStudy (lexi724):

thanks, would it be okay if i asked another

OpenStudy (lexi724):

f parallelogram ABCD was reflected over the y-axis, reflected over the x-axis,and rotated 180°, where would point A' lie? (-4,1) (1,-1) (1,1) (-4,-1)

OpenStudy (lexi724):

i say A or D

OpenStudy (anonymous):

for the first question J'(-2,-6) M' is (1,-5)

OpenStudy (anonymous):

I know the correct answer is A....

OpenStudy (lexi724):

so why didnt you try to correct me? @RaymondoOnley Also will someone help me with the third question

OpenStudy (lexi724):

What's ur third question?

OpenStudy (anonymous):

I'm working on answering your question still, Lexi. :)

OpenStudy (anonymous):

(-4,1)

OpenStudy (lexi724):

What set of reflections and rotations would carry rectangle ABCD onto itself?

OpenStudy (lexi724):

reflect over the y-axis, reflect over the x-axis, rotate 180° rotate 180°, reflect over the x-axis, reflect over the line y=x reflect over the x-axis, rotate 180°, reflect over the x-axis rotate 180°, reflect over the y-axis, reflect over the line y=x

OpenStudy (lexi724):

this is the next one

OpenStudy (anonymous):

The answer is A. for the 3rd question you asked.

OpenStudy (anonymous):

I'm sorry but I can't answer this last question for you because I have homework myself. :)

You have to draw a graph or use graph paper then follow the directions.

OpenStudy (anonymous):

If you do that, the you'll see the correct answer.
