The Lakeside Marina charges a $35 rental fee for a boat in addition to charging $15 an hour. Write an equation in slope intercept form for the situation. For how long could you rent the boat if the cost is $80?
pls answer

3 hours

Step-by-step explanation:

y = mx + b

for each hour you are charged 15 dollars. for every 1 hour, you are charged $15.

y = 15x

you must also add the base fee of 35

y = 15x + 35

if you know that y = 80,

80 = 15x + 35

solve for x

x = 3

35 + 15=50

Step-by-step explanation: this is just for part 1

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
