Question
**Problem Statement:** Find all second-order partial derivatives for the function \( r = \ln |7x + y| \). **Partial Derivatives:** \( r_{xx} = \) \(\underline{\quad\quad}\) \( r_{xy} = \) \(\underline{\quad\quad}\) \( r_{yx} = \) \(\underline{\quad\quad}\) \( r_{yy} = \) \(\underline{\quad\quad}\) **Explanation:** This exercise requires finding the second-order partial derivatives of the given function. We denote these derivatives as \( r_{xx} \), \( r_{xy} \), \( r_{yx} \), and \( r_{yy} \). Each designation represents taking the partial derivative with respect to the given variables in sequence: \( r_{xx} \) is the second partial derivative with respect to \( x \), \( r_{xy} \) and \( r_{yx} \) are mixed partial derivatives, and \( r_{yy} \) is the second partial derivative with respect to \( y \).
