Suppose you have a square matrix a for which det (a)? o. tell whether each of the following is true or false. support your answer (a) (2 points) a-1 exists (b) (2 points) a is invertible (c) (2 points) ar-0 has exactly one solution (d) (2 points) at has no solution. (e) (2 points) the reduced row echelon form of a has a row of zeros in (f) (2 points) the columns of a are linearly independent

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

the answer would be 484
