Determine whether the matrix is in row. echelon form. if it is, determine whether it is also in reduced row echelon form. 001001 00010 doo 10 step 1: check rows consisting entirely of zeros. do all rows (if any) consisting entirely of zeros occur at the bottom of the matrix? yes no there are no rows consisting entirely of zeros. step 2: check the first nonzero entry of each row. does each row that does not consist entirely of zeros have the first nonzero entry equal to 1? yes no there are no rows that do not consist entirely of zeros. step 3: check successive nonzero rows. if each nonzero row has a leading 1, is the leading 1 in the higher row farther to the left of the leading 1 in the lower row for each pair of successive rows? yes no there exists at least one row which does not have a leading 1. step 4: check the columns with leading ones. does every column with a leading 1 have zeros in every position above and below its leading 1? • yes no step 5: determine the form of the matrix. select all that apply.) row. echelon form reduced row-echelon form neither
