Answer:
y=25x+50
Step-by-step explanation:
The rental rate for a power washer has a one time fee of $50 plus $25 for each day of the rental.
let x be day of rental n y be the total cost of rental
with 0 day (x=0), the one time fee means y=50 which is the y-intercept
$25 per day means the slope is 25
combining y = 25x + 50
21 8/9 because you need to make both fractions have a common denominator so you multiply the top and bottom of 1/3 by three to get 3/9 and then you add to get 21 8/9
Combine the like terms.
4x^4+3x^3-16x^2+27x-18
