Given lines ac and de are parallel, which pair of angles are
not congruent to each other?
a) hbc and abe
b) cbe and hba
c) deg and bef
g) gef and feb

.

step-by-step explanation:

probability for j is 1/4

while

a is 1/6

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.
