Answer 10

yep its A and C

Answer 11

are you positive? did you get the exact question and picture?

Answer 12

question yes picture no but it looks like a triangle thats all

Answer 13

can you take a screenshot? sorry i just cant fail it again

Answer 14

if i'm wrong very very sorry:(

Answer 15

but cross fingers :)

Answer 16

Parallelogram WXYZ and parallelogram are congruent.

Which sequence of transformations could have been used to transform parallelogram WXYZ?




A.
Parallelogram WXYZ was reflected across the y-axis and then translated 2 units right and 3 units down.

B.
Parallelogram WXYZ was translated 2 units right and 3 units down and then reflected across the y-axis.

C.
Parallelogram WXYZ was rotated 90° clockwise around the origin and then translated 1 unit left and 4 units down.

D.
Parallelogram WXYZ was rotated 270° counterclockwise around the origin and then translated 5 units left.

how about this one? @studydino1201

Answer 18

hold on

Answer 19

i got that one, how about this
