Answer:

Step-by-step explanation:
In the equation: 
x's can be simplified and y's can be simplified!
Always remember that for exponents, you subtract the powers when dividing
so for x: 15-8 = 7
for y: 9-3 = 6
so the final answer is: 
Answer:
No

Answer: (-1, 1)</h3>
=========================================================
Explanation:
The rotation rule we use is 
The x and y coordinates step places, then the second coordinate (after the swap) changes in sign from positive to negative, or vice versa.
For example, the point (5,7) rotates to (7, -5). As another example, (2,-1) becomes (-1, -2). As another example, (-9,4) becomes (4,9).
----------------------------------
In our case, the point (-1,-1) will rotate to (-1, 1)
Note: A 270 degree counterclockwise rotation about the origin is the same as a 90 degree clockwise rotation about the origin. Refer to the diagram below.
