Alocal car wash is inviting customers to join the concierge club, in which you can have your car washed as many times as you wish for a fixed monthly fee. amy creates the graph below to compare the cost per wash versus the cost for the concierge club. which conclusion is supported by the graph?

I'm pretty sure the answer is D. You can see that 6 washes is 30 dollars so that would make each wash $5 and all other answers can be proven wrong or not proven to be true.

Answer is Choice D, that the pay per wash is 5.00 per wash.

Step-by-step explanation:

Since that is the only point marked (6,30) you divide the total cost (30) by (6) and you get 5.00.

answer: ok

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
