Cargo plane flew from the us across the atlantic at 242 mph and flew back to us at 262. given that the first trip took two hours longer, how long was the return trip

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

slope is 35 and 20 miles is the y-intercept.

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.

step-by-step explanation:

6e14 is the answer.
