Jack and Jim are playing tug of war. The ribbon at point B is tied at the midpoint of the rope. The length of AB can be represented x + 15, and the length of BC can be represented by 2(x - 5). What is the length of AB? (GM.2)​

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.
