Identify and write the angles in the figures below. If there are none of that angle, write none. If there is more than one of the same type of angle, write only one example. Identify if the figure has parallel lines or perpendicular lines, and write ‘Yes’ or ‘No’.

idk man good luck man

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 answer is c 150
