Solve the proportion

12/16 = 3z/4

z = 1

Step-by-step explanation:

12/16 = 3z/4

=> 12 x 4/16 = 3z

=> 3z = 12 x 4/16

=> 3z = 12 x 1/4

=> 3z = 3

=> z = 1

what type of question is thiss

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.
