the rental rate for a power washer has a one time fee of $50 plus $25 for each day of the rental.

the graph shows points representing the total cost of the rental.
which linear equation, in slope-intercept form, that models the total cost of the rental over time?

a. y=75xy=75x

b. y=25x+50y=25x+50

c. y=x+50y=x+50

d. y=25xy=25x

e. y=50x+25

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
