Answer:
1. Inverse of matrix A exist If and Only If
c. the determinate does not equal zero
2. The inverse of matrix A
a.does not exist
Step-by-step explanation:
Given:
Consider matrix A. 2 by 2
A=[tex]\left[\begin{array}{cc}1&1\\1&1\end{array}\right][/tex]
To Find:
Does the inverse of matrix A exist?
Solution:
1. Inverse of matrix A exist If and Only If
c. the determinate does not equal zero
For the Given Matrix A We have
Det |A| = 1×1 -1×1
Det |A| = 0
2. The inverse of matrix A
a.does not exist
