((10 points need answer)) the figure shows three quadrilaterals on a coordinate grid: which of the following statements is true about the three quadrilaterals? a: u and w are similar but not congruent. b: u and v are similar and also congruent. c: u and v are similar but not congruent. d: v and w are similar and also congruent.

C

Step-by-step explanation:

The two rectangles look similar, but they are not the same since one of them is larger due to a dilation.

the transverse axis of a hyperbola is the line that contains the two vertices and the two focuses.

in this example (hyperbola of equation x^2/2 - y^2/4 = 1), the transverse axis is the  x-axis  . 

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.
