A school club spends $75 on supplies to set up a car wash fundraiser. The students are going to charge $6.00 per car. Write a linear model in the form y=mx+b where y represents the amount of profit the students earn for washing x number of cars.

Y=6x-75

Step-by-step explanation:

If you take the beginning amount spent which is $75 you would want that on the graph to be in the negatives. With it starting in the negatives it will show you whether the amount of cars (x) will cause a profit or a deficit.

For instance, say they washed 7 cars (x=7). You would take 6 and multiply it by 7 to get 42. Then you would take 42 and take away 75 to find the profit/deficit. 42-75= -33

This shows that washing 7 cars will cause them to lose $33.

If you take another situation where they wash 15 cars (x=15). In this case they would earn a total of $15.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's
