For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.
For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function

Answer:
37 children
Step-by-step explanation:
to find how many students there were you are going to divide 888 by 24 so there are 37 children. that is one way another way is to draw it as a fraction so have it like this 888/24
VARIABLES:
[x] Yearbook Club (expression: x)
[y] Drama Club (expression: x + 12)
EQUATIONS:
#1 x + y = 72
#2 y = x + 12
Now we shall use the method of substitution to solve.
FINDING X:
#1 x + (x + 12) = 72
#2 2x + 12 = 72
#3 2x = 60
#4 x = 30
The amount of students in the yearbook club: 30
The amount of students in the drama club: 72 - 30 = 42
If you can, please give me brainliest. Thank you!
