Answer:
3
Step-by-step explanation:
the initial statement is
y ∝ 1 /x
to convert to an equation multiply by k the constant
of variation
y = k × 1 /x = k /x
to find k use the given condition
y = 5 when x = 6
y = k/ x ⇒ k = y x = 5 × 6 = 30
y = 30 /x
when
x = 10
then
y = 30 /10 = 3
Answer: y = 3
Step-by-step explanation:
In inverse variation, as one variable increases, the other variable decreases and as one variable decreases, the other increases.
We would introduce a constant of proportionality, k. Therefore,
y = k/x
When y = 5 , x = 6
Therefore,
5 = k/6
Cross multiplying by 6, it becomes
k = 6 × 5 = 30
The expression becomes
y = 30/x
Therefore, when x is 10,
y = 30/10
y = 3
