A fisherman can route upstream at 1 mph and downstream at 4 miles an hour he started rowing upstream until he got tired than Road downstream to his starting point how far did the fisherman row if the entire trip took 2 hours

answer: can and shows the work

step-by-step explanation:

you probably already have the answer but anyways it's b. 15.0

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.
