Subtract the powers
c. 9-7 so 10^2
d. 8-1 so 5^7
So to answer this question all you need is the definition of a reflection
A reflection in my explanation is a flip of the figure to be on the opposite side NOT changing the shape but only flipping the coordinates
A + b = 45
a - b = 21
a = 21 + b
Use substitution
21 + b + b = 45
2b = 24
b = 12
45 - 12 = 33
The numbers are 33 and 12
