Aboat takes 4 hours to go 20 miles upstream. it can go 32 miles downstream in the same time. find the rate of the current and the rate of the boat in still water.

upstream

4(boat-current) = 20

(boat-current)=5

 Downstream

4(boat + current) = 32

(Boat + current)=8

Boat + current = 8

Boat – current =5

2 boat = 13

 Boat = 13/2 = 6.5 miles per hour in still water

6.5 + current = 8

Current = 8-6.5 = 1.5 miles per hour

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

i think asking google will you get the answer to that question
