Question

Help me please I need it !!!

Answer 1

If x and y are inversely related then :

$\bigstar\;\; \boxed{\mathsf{x \propto \dfrac{1}{y}}}$

$\bigstar\;\; \boxed{\mathsf{\dfrac{x_1}{x_2} = \dfrac{y_2}{y_1}}}$

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

Substituting the values, We get :

$:\implies \mathsf{\dfrac{5}{15} = \dfrac{y}{2}}$

$:\implies \mathsf{\dfrac{1}{3} = \dfrac{y}{2}}$

$:\implies \mathsf{y = \dfrac{2}{3}}$

$:\implies$  y = 0.67

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