<span>A. When adding two rational numbers a/b and c/d, the numerators a and c do not have to be integers. Therefore, the sum does not have to be a rational number. I think this is right might nor be :/

For something to be a function, the input (x value) can ONLY HAVE ONE output (y value), so if x has multiple outputs, it is not a function
B is not a function because x = 2 and x = 9 has 2 outputs
Your answer is A
Answer:
-2
Step-by-step explanation:
Remember to follow PEMDAS. First solve parenthesis, power, multiplication, then add.
(5 - 2) = 3
(-4)² = (-4)(-4) = 16
3(-6) = -18
16 + (-18) = 16 - 18 = -2
-2 is your answer.

No the answer is 89 because 97 - 8 is 89
