Question

Help me please I need it !!!

Answer 1

If x and y are inversely related then :

`\bigstar\;\; \boxed{\mathsf{x \propto (1)/(y)}}`

`\bigstar\;\; \boxed{\mathsf{(x_1)/(x_2) = (y_2)/(y_1)}}`

Given : x₁ = 5 and x₂ = 15 and y₁ = 2 and y₂ = y

Substituting the values, We get :

`:\implies \mathsf{(5)/(15) = (y)/(2)}`

`:\implies \mathsf{(1)/(3) = (y)/(2)}`

`:\implies \mathsf{y = (2)/(3)}`

`:\implies` y = 0.67

Answer : When x = 15
`:\implies` y = 0.67
