Question

Determine the coefficient matrix of the system of equations latex: 3x-2y = 7,\; x+4y=2. 3 x − 2 y = 7 , x + 4 y = 2. what is the determinant? g

Answer 1

A. 0

Explanation:

Answer 2

When put in matrix form, the coefficients of

... 3x -2y = 7

... x + 4y = 2

look like

`\left[\begin{array}{cc}3&-2\\1&4\end{array}\right]`

The determinant is 3×4 - 1×(-2) = 14.
