Answer:
12-111=-99
Step-by-step explanation:
If y+6=15, then y=9. (9+6)divided by 3 would be 5, not 15.
The answer is B because 5^3 is 125 so the approximate answer is 124.75

Answer: Yes
Step-by-step explanation:
To solve this, imagine you have a vertical line. You can use a ruler or something straight. Move the ruler across the screen. Does the ruler intersect 2 points at once? If so, then it is not a function. If it only intersects one point, then it is a function.
Always remember: a function cannot have two x's with different y-values.
Hope that helped!
