Question

Assume that y varies inversely as x. If

Y
y = 10 when
=
x = 4, what is the value for y when
x = 6?

Answer 1

6.67

Step-by-step explanation:

10=4

y=6

10×4/6

Answer 2

x=5

Step-by-step explanation:

y∝1x∴y=k⋅1x∴x⋅y=k;

When x=4;y=10∴4⋅10=kork=40.

So variation equation is x⋅y=40

When y=8;x=408=5∴x=5 [Ans]

Step-by-step explanation:
