Suppose that y varies inversely with x, and y = 6 when x = 8. What is an equation for the inverse variation? (1 point)
The inverse variation between y and x can be expressed as y = k / x where k is the constant of inverse variation. From the given, the equation is,
6 = k / 8
The value of k is 48. Thus, the final equation is,
y = 48 / x
Answer:
\(y= \frac{48}{x}\)
Step-by-step explanation:
Suppose that y varies inversely with x, and y = 6 when x = 8.
y varies inversely with x so the equation is y= k/x
where k is the constant of proportionality
Lets plug in y=6 and x=8 to find out k
\(y= \frac{k}{x}\)
\(6= \frac{k}{8}\)
multiply both sides by 8
48 = k
Now to get the equation of inverse variable plug in k= 48
\(y= \frac{48}{x}\)
