From the sets of length measurements given below, write the sets that could be the lengths of the sides of a triangle. ) 4.2 cm , 5.3 cm. 6 cm (ii) 12.3 cm. 5.7 cm. 6.6 cm (ii) 8.5 cm , 3.7 cm. 4.3 cm (iv) 15 cm. 9 cm, 12 cm​

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:

x= cost per bracelet

number of bracelets * x + shipping charge = total cost

so

9x+9=72

b. is true. hope this . happy
