I'm doing practice with those exercises

H Using row operations, determine the value of b so that the matrix K = co of to is the augmented matrix of a consistent linear system. Justify.Let M be the matrix 100 0 0 1 ) . a) Find a matrix P whose RREF is M. ) Is there a matrix F, whose entries are all odd numbers, and whose RREF is M? Explain.Let A be the matrix below. Determine if A is in RREF and, if not, find its RREF. Use the RR.EF of A to describe concretely and precisely the solution set of the homogeneous system AT = 0. If there are multiple solutions the description should be given in terms of free variables
