# Suppose that y varies inversely with x. Write a function that models the inverse function. x = 1 when y = 12?

##
y=1/12 x

y=12/x

y=1/12x

y=12x

y=1/12 x

y=12/x

y=1/12x

y=12x

#### Answer:

#### Explanation:

The statement is expressed as

#yprop1/x# To convert to an equation introduce k, the constant of variation.

#rArry=kxx1/x=k/x# To find k use the condition that x = 1 when y = 12

#y=k/xrArrk=xy=1xx12=12#

#rArry=12/x" is the function"#
