x=47°

y=43°

z=133°

Step-by-step explanation:

x=x

z=3x-8

x+3x-8=180

4x-8=180

4x=188

x=47

z=3x-8=3(47)-8=141-8=133

y=90-x=90-47=43

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.
