If the given triangles are similar, the values of x and y are

x = 20, y = 6

Step-by-step explanation:

Δ ACB and Δ DCE are similar, so the ratios of corresponding sides are equal, that is

= , substitute values

= ( cross- multiply )

15x = 300 ( divide both sides by 15 )

x = 20

and

= , substitute values

= ( cross- multiply )

25y = 150 ( divide both sides by 25 )

y = 6

d

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.
