What is the constant of variation, k, of the direct variation, y = kx, through (–3, 2)? k = –k equals negative StartFraction 3 Over 2 EndFraction. k = –k equals StartFraction 2 Over 3 EndFraction. k = k equals StartFraction 2 Over 3 EndFraction. k = k equals StartFraction 3 Over 2 EndFraction.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

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.
