Given the matrix A [1 7 L3 6 91 5 2. 4 8] (a) Find the inverse of the matrix A clearly showing all the steps leading to the inverse matrix. (b) Show clearly using matrix multiplication that AA-1 = I and A-1A = I, where I is the identity matrix.
linear algebra Recall the Rank Theorem, which states that if A is an mxn matrix, then rank(A) + nullity(A) = n. Recall the given matrix A. A = [ 3 -6 0 3 11 -1 2 1 3 6 [ 2 -4 1 6 7 This is a 3 x matrix, so n = . Furthermore, we previously determined that rank(A) - 2. Substitute these values into the formula from the Rank Theorem and solve for nullity(A). rank(A) + nullity(A)...
