For questions 2 and 3, let A =
Compute det(A) using the definition of determinant.
Compute det(A) using row operations.
Find a matrix A whose inverse is B.
True or false? Justify your answer. All matrices are "X".
If the equation Av = h is consistent, then A is invertible.
If the columns of A are linearly independent, then A is invertible.
If det(A) = 2, then det(3A).
