A way that I use to determine if something is a function or not is to ask whether or now it passes the “vertical line test”. In other words, does an x have two y’s? if we graphed these points, and proceeded to draw a vertical line through it, if it touches the function twice, then it is not a function. So I believe your answers would be A and C (In A, when x is 2, there are two y’s. Same goes with C, when x is 1, 4, 9 etc).
I hope this answer helps! :)
Answer:
90 tens
Step-by-step explanation:
We know that there are 10 tens in a hundred, so this will be our unit rate for the rest of this problem. Since we have 9 hundreds, we have to multiply by 10 to get our answer.
9 × 10 = 90
The answer to our question is 90 tens are in 9 hundreds.
Answer: 4,578
Step-by-step explanation:
654 calories x 7
Answer:
Step-by-step explanation:
First, we will find the midpoint for the x - coordinate first.
Midpoint (x) = 
Now we will find the midpoint for the y - coordinate.
Midpoint (y) = 
Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)
