Dilate triangle QRS on the coordinate plane using the origin (0,0) as center of dilation and a scale factor of three of 3 to form triangle Q'R'S. Label the coordinates of points Q'R', S' and S'

11

step-by-step explanation:

32.50-7.50=25

225/25=11

it would take 7/10 of an hour too fill the pool.

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.
