Answer 2

What set of transformations is performed on ABCD to form A′B′C′D′?

A translation 1 unit to the left followed by a 180-degree counterclockwise rotation about the origin
A translation 1 unit to the right followed by a 180-degree counterclockwise rotation about the origin
A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the right
A 90-degree counterclockwise rotation about the origin followed by a translation 1 unit to the left

Answer 3

Well we see that the pre-image of the trapezoid is two units from y = 0 while as the image is 1 unit from y = 0 that would mean that the trapezoid first translated 1 unit to the left...

Answer 4

So would it be

a
b
c
or
d?

Answer 5

One second.

Now we know that it translated the the left by unit 1st...Now if it did perform a 180 degree counterclockwise rotation about the origin that would mean that the coordinates would change...

\(\huge{(x,y) \rightarrow (-x,-y)}\)

We see that our coordinates are infact with negative x and y values that would mean that it did in fact complete a 180 degree clockwise turn after a translation of 1 unit to the left...

thank you so much:)
