Answer:

Step-by-step explanation
Given f is a direct variation equation (Direct variation is when one variable is equal to a constant times another variable, with no additions or subtractions alongside).
Now by the above condition let the constant be "c".Then

also given that
when
on substituting the above values,



Therefore our equation is 
Answer: -3/5
Step-by-step explanation: -3^3 is 27 and 5^3 is 125. So when you find the cube root of this equation you just simplify it to that.
4+5=9
24 divided by 9=2.6
2.6x4=10.4
2.6x5=13
= 10.4:13
I hope thats right
sorry if not but i think it is
