Just divide and get the answer
Answer:
y = 40 / x^1/3
Step-by-step explanation:
Given that :
y α x^1/3
y = k * 1 / x^1/3
y = k / x^1/3
When x = 125 ; y = 8
8 = k / 125^1/3
Cube root of 125 = 5
8 = k / 5
8 * 5 = k ; k = 40
Hence, expression becomes :
y = 40 / x^1/3
4 + y = 19
y = 19 - 4
y = 15
Answer:
The sign should be negative ( - )!
Step-by-step explanation:
-4 - 8 = -12
