The scale of the map is missing. the actual distance from liberty to west quall is 72 miles, and it is 6 inches on the map. what is the scale of the map? foston is between liberty and west quall and is 4 inches from liberty on the map. how far is foston from west quall?

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:

the correct answer is $7.38
