Answer:
Y=41/30 + j/60
Step-by-step explanation:
There is a rule:
One input(x-value) can only have one output(y-value) in order to be a function.
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
(2,10),(4,15),(6,20),(8,25)
This is a function because each input only has one output.
Your answer is A

Answer:

Step-by-step explanation:
I think you have the situation shown in the diagram below.
1. Calculate the value of n

2. Calculate the value of YZ

We need to write a proportion to solve this
7/3=35/x
105=7x
divide each side by 7
15=x so, there were 15 burgers without cheese.
We could add the cheese burgers 35 to burgers without cheese 15
35+15=50 burgers were sold.
