Problem 8) B
Step-by-step explanation:
Recall that inverse variation has the form:
Where <em>k</em> is the constant of variation.
Problem 7)
We are given that <em>y</em> = 39 when <em>x</em> = 1/3. Thus:
Solve for <em>k: </em>
<em /><em />
<em />
Hence, our equation is:
Then when <em>x</em> = 26, <em>y</em> equals:
Problem 8)
We are given that <em>y</em> = 25 when <em>x</em> = -1/5. Thus:
Solve for <em>k: </em>
<em /><em />
<em />
Hence, our equation is:
