Which expression makes the equation true? 1.) y^20 = ( )^2 a.) y^4 b.) y^5 c.) y^10 d.) y^12 2.) 100m^20 = ( )^2 a.) 10m^20 b.) 10m^10 c.) 50m^10 d.) 50m^20

d

step-by-step explanation:

i used the pitagoras theoreme

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.
