question 40

Multiple Choice

Determine whether the variation model is of the form $y = k x$ or $y = \frac { k } { x }$ and find k.Then write a model that relates y and x.
$$\begin{array} { | c | c | c | c | c | c | } \hline x & 5 & 10 & 15 & 20 & 25 \\\hline y & 26 & 13 & \frac { 26 } { 3 } & \frac { 13 } { 2 } & \frac { 26 } { 5 } \\\hline\end{array}$$

• A) \(y = \frac { 130 } { x }\)
• B) \(y = \frac { x } { 130 }\)
• C) \(y = \frac { 1 } { x }\)
• D) \(y = 130 x\)
• E) \(y = x\)
