Answer:

Step-by-step explanation:
We are given the equations
to search for a value of
that yields an equivalent statement.

Do you have step one? maybe i can try it but im not that good in math
Okay so you would use PEMDAS (parentheses, exponents, multiply, divide, add, and subtract) so there are no parentheses so you do the exponents

then you do the rest so 100+36=136 and then 136-9=127 so the answer is 127
Answer:
Reflected about the y-axis and then rotated 90° counterclockwise
Step-by-step explanation:
(x , y) to (-x , y) --> reflected over y-axis
then (-x , y) --> (-y, -x) -->90 degrees rotation counterclockwise
So answer is the last one
Reflected about the y-axis and then rotated 90° counterclockwise
Answer:
A'(2, 6 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply each of the coordinates by 
A(3, 9 ) → A'(
(3),
(9) ) → A'(2, 6 )
