To find the inverse of the relation \( y = 10x \), we need to express \( x \) in terms of \( y \).
Starting with the equation:
\[ y = 10x \]
We can solve for \( x \) by performing the following steps:
- Divide both sides by 10:
\[ x = \frac{y}{10} \]
Now, to express this as the inverse relation, we replace \( x \) with \( y \) and \( y \) with \( x \):
\[ y = \frac{x}{10} \]
Thus, the inverse of the relation \( y = 10x \) is:
\[ y = \frac{x}{10} \]
