Select the correct answer from each drop-down menu. A system of equations and its solution are given below.

System A

Complete the sentences to explain what steps were followed to obtain the system of equations below.

System B

To get system B, the
second
equation in system A was replaced by the sum of that equation and
times the
equation. The solution to system B
the same as the solution to system A.

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.
