Answer:
y = 20
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k use the condition y = 8 when x = 5, then
k = yx = 8 × 5 = 40
y = [tex]\frac{40}{x}[/tex] ← equation of variation
When x = 2, then
y = [tex]\frac{40}{2}[/tex] = 20
Answer:
- y=1/x
- y=k/x
- k=yx
- given y=8, x=5
- k=8×5=40
- finding y when x=2
- y=40/2=20ans
