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.

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be
