INVERSE VARIATION

EQUATION:

[tex]y = \frac{k}{x} [/tex]

––––––––

First, find the constant of variation k using the formula k=xy.

[tex]23 = \frac{k}{8} [/tex]

[tex]k = (8)(23)[/tex]

[tex]k = 184[/tex]

––––––––

Then, find y if x is equal to four using the formula y=184/x.

[tex]y = \frac{184}{x} [/tex]

[tex]y = \frac{184}{4} [/tex]

[tex]y = 46[/tex]

Final Answer:

y = 46
