2. The prices of different burgers are shown on this sign. Based on the information from the menu, is the price of a burger a function of the number of patties?

If this is what your question is, yes the price of the burger is a function of the number of patties.

Step-by-step explanation:

This is because, the number of patties is the independent variable and the price is the dependent variable. A function can be written as y = f(x), here x is the number of patties. The price of the burger is y. I had this question that is also why I know this is right.

I hope this helps and have a nice day..

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

i think the answer is b.

step-by-step explanation:

not 100% sure though.
