Good evening ,
______
Answer:
y=15x and y= -x
___________________
Step-by-step explanation:
y=15x represents a proportional relationship because y/x=15
y= -x represents a proportional relationship because y/x= -1.
:)
The answer is 13 because you do proportion
The answer is: "7.268 cm" .

Since the formula for the volume, "V", of a cube, is:
V = s³ ;
in which: "s" = side length of a cube;
Given: "V = 384 cm³ " ; Plug this value into the formula; to solve for "s" ;
V = s³ ;
↔ s³ = V ;
s³ = V ;
s³ = 384 cm³ ;
Take the "cubic root" of EACH SIDE of the equation; to isolate "s" on one side of the equation ; & to solve for "s" ;
_________________________________________________
∛(s³) = ∛ (384 cm³) ;
s = 7.2684823713285586 cm
Round to: 7.268 cm .
