Use Determinants to Identify Inconsistent Systems and Systems with Dependent Equations
-$$\begin{array} { l } 
- 4 x - 6 y = 8 \
- 8 x - 12 y = 6
\end{array}$$
A) system is inconsistent
B) system contains dependent equations

Quizplus · Accepted Answer

The determinant of the coefficient matrix is 0, which indicates that the system is inconsistent.

Use Determinants to Identify Inconsistent Systems and Systems with Dependent −4x−6y=8−8x−12y=6\begin{array} { l } - 4 x - 6 y = 8 \\- 8 x - 12 y = 6\end{array}−4x−6y=8−8x−12y=6​
