Which statement is the converse of the following?
if two angles form a linear pair, then they are supplementary.
a. if two angles are supplementary, then they form a linear pair.
b. if two angles do not form a linear pair, then they are not supplementary.
c. if two angles are not supplementary, then they do not form a linear pair.
d. if two angles form a linear pair, then they are supplementary.

c

step-by-step explanation:

because of the levels

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.
