X/5=15/3 in this proportion which number is equal to x in the proportion

x = 25 because...

if 15/3 = 5

then you would: multiply 5 x 5 = 25

so... x = 25

Hope this helped!!!

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

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.
