The following table represents the number of tickets purchased at a movie theater and cost of purchase. the number of tickets purchased varies directly with the total costs of the purchase. determine the constant variation

1) $24.00
2)$0.17
3)12.00
4)$6.00

4)$6.00

Step-by-step explanation:

If you set up an equation you can plug in all of the answer choices and try to find which one will make the equation true. Try using the equation x(2)=12 or x(4)=24 or x(6)=36 or x(8)=48. Any of them will work if you just plug in $6.00 but you can also try the other answers to be sure.  

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
