A business owner uses a ${}2 imes 2$ matrix to represent the relationship between sales and inventory costs: $\begin{bmatrix} 5 & -3 \\ 2 & -4 \end{bmatrix}$. To perform a financial analysis, the owner needs to calculate the determinant. According to the formula for a ${}2 imes 2$ matrix, which of the following expressions shows the correct initial setup for this calculation?

An operations manager is using the matrix $\begin{bmatrix} 5 & -3 \\ 2 & -4 \end{bmatrix}$ to model the efficiency of two production lines. To verify the system's stability, the manager identifies the numerical results of each step in the determinant calculation. Match each part of the calculation with its correct result based on the standard procedure.

An operations analyst uses the matrix $\begin{bmatrix} 5 & -3 \\ 2 & -4 \end{bmatrix}$ to model the output variability between two shifts. To complete the stability check, the analyst calculates the determinant of the matrix. Based on the standard procedure for a ${}2 \times 2$ matrix, the resulting numerical value of the determinant is ____.

A logistics coordinator is using the matrix $\begin{bmatrix} 5 & -3 \\ 2 & -4 \end{bmatrix}$ to analyze route efficiency. To find the determinant of this ${}2 \times 2$ matrix, the coordinator must follow a standard procedural sequence. Arrange the following steps in the correct order to evaluate this determinant.

A small business owner uses the matrix $\begin{bmatrix} 5 & -3 \\ 2 & -4 \end{bmatrix}$ to represent the relationship between advertising expenses and revenue growth. After applying the formula for a ${}2 \times 2$ determinant, the owner calculates the final value to be -14. True or False: This is the correct determinant for the given matrix.
