Does have an inverse? Why or why not?

Does Have An Inverse Why Or Why Not class=

Sagot :

A

A square matrix is invertible if its determinant is not zero.

The determinant for this matrix is

[tex]\begin{vmatrix}4&8\\7&14\end{vmatrix} = 4\cdot14 - 8\cdot7 = 56 - 56 = 0[/tex]

so it does not have an inverse because its determinant is zero.
