3× + 4 = 12 - × 4× + 1 = × + 13
2× - 15 = 5 - 2×
-3 × - 1 = 15 - 5×
2× - 6 = - 24 - 7×
-8× - 7 = 50 - 5×
5× - 7 - × = 9
2× + 9 = × + 9
5× + 5 = 2× - 1
-2× - 3 = 18 + 5×

no one knows lol

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.

i don't think there is enough
