Parallelogram abcd is translated (x + 3, y − 2) and then rotated 90° about the origin in the clockwise direction. complete the table to show the locations of a″, b″, c″, and d″ after both transformations.
parallelogram abcd is shown. a is at negative 5, 1. b is at negative 4, 3. c is at negative 1, 3. d is at negative 2, 1.
a (− 5, 1) a″ ?
b (−4, 3) b″ ?
c (−2, 3) c″ ?
d (−1, 1) d″ ?
a″ (−1, 2), b″ (1, 1), c″ (1, −2), d″ (−1, −1)
a″ (1, −2), b″ (−1, −1), c″ (−1, 2), d″ (1, 1)
a″ (−2, −1), b″ (−1, 1), c″ (2, 1), d″ (1, −1)
a″ (1, 1), b″ (−1, 2), c″ (−1, −1), d″ (1, −2)

The answer is A″ (−1, 2), B″ (1, 1), C″ (1, −2), D″ (−1, −1)
Step-by-step explanation:
I took the test and got the answer right
Ответ:
The answer is A
Step-by-step explanation:
So the original coordinates are given
Now for (x + 3, y - 2)
A"= (-2,-1)
B"=(-1,1)
C"=(2,1)
D"=(1,-1)
A rotation of 90 degrees clockwise states that the x coordinate of the pre-image will be the -y coordinate of the new image, and that the y coordinate of the pre-image will be the x coordinate of the new image.
So the final coordinates of the parallelogram will be as stated:
A"=(-1,2)
B"=(1,1)
C"=(1,-2)
D"=(-1,-1)
I hope this helps pls mark brainliest.
