False Question 8 (1 point) Saved Suppose A is an invertible 2x2 matrix. What can we conclude about the determinant of A? det(A)=0 detta) 1 detAll or det)-1 None of the above Question 9 1 point that is the mateix Let u-(a,b), v=(c,d), and suppose that A is the matrix a A b d Which statement is correct? O if u and v are on the same line the det(A)=0 If u and v are not on the same line then det(A)-1 If u and v are not on the same line then det(A)-0 If u and v are on the same line then det(A)=1
