6y+y(4)
7y(4)
y=4/7
Youre welcome
The answer A because I did the math and y is -20 and x is -12
Answer:
1. Reflection
2. rotation and reflection
3. b', b''
4. 26.3
Step-by-step explanation:
1. It is like looking in a mirror. Its is being reflected across the y axis
2. It is rotated 90 degrees to the right. Then reflected over the x axis.
3. they are the same
4. It is the same as A" B" C" D" so the lengths are the same and you just add them.
Step-by-step explanation:
The correct step to simplify this expression is (9^7)^3=9^21
