I will give BRAINIEST A map has a scale of 2 inches = 20 kilometers. If the distance between two cities on the map is 10 inches, what is the actual distance between the cities?
a.
120 km
c.
100 km
b.
150 km
d.
10 km

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.

answer: -0.5 would be the most likley outcome
