Express the inverse of the following matrix (assuming it exists) as a matrix containing expressions in terms of k. If your answer contains fractions, be sure to include parentheses around the numerator and/or denominator when necessary, e.g. to distinguish 1/(2k) from 1/2k. You can resize a matrix (when appropriate) by clicking and dragging the bottom-right corner of the matrix. 1-1-1-1 -50k -19 4 4 000 A 000 080
