Awater barrel has two pipes for filling (a and b) and one pipe for draining (c). if only pipe a is open, the empty barrel will fill in 1 hour. if only pipe b is open, the empty barrel will fill in 50 minutes. if only pipe c is left open, the full barrel will empty in 40 minutes. suppose that all three pipes are left open when the barrel is initially empty. how many minutes will it take to fill? round your answer to the nearest minute.

The answer I came up with is 1 hour and 50 mins meaning in total is 110 mins hope this is correct and helps

Step-by-step explanation:

answer: x=3 and y=4

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
