Answer:
8x+10y cannot be simlified because they do not have a common variable
so until you find the value for x and y u cannot simplify
(5,7)
translate down by 4:
(5,3)
reflect over y (so invert x-coordinate):
(-5,3)
It would be 10 because if you round the 9 by the 7 you would make the 9 into a 10.
Answer:
b. (16 , 4)
Step-by-step explanation:
f(x): 0 -> 1 , 4 -> 16
f⁻¹(x): 1 -> 0 , 16 -> 4
