If y varies inversely with x, and y = 48 when x = 6, find y when x = 18.

y = 16

Step-by-step explanation:

Given that,

y varies inversely with x i.e.

Where

k is a constant of proportionality

Put y = 48 and x = 6 in the above equation to find k.

So,

Now put k = 288 and x = 18 in the above equation to find y.

So, the value of y is equal to 16 when x = 18.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140
