Super fast pls a rectangular cardboard has dimensions as shown. the length of the cardboard can be found by dividing its area by its width. what is the length of the cardboard in inches? rectangle with width labeled on the right, width equals 4 and 1 over 2 inches. below the rectangle, it says, length equals question mark. inside the rectangle, it says area equals 36 and 3 over 4 square inches

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.

step-by-step explanation:
