Solve for t. |t t -2 7] = -9

Consider a matrix A = (a) Find a basis and dimension for the space Sc spanned by the columns of the matrix A. e.g. Sc = span (b) Find a basis and dimention for the space SR spanned by the rows of the matrix A, e.g. SR = span (c) Is = dim(SR) = dim(SC)?

Given A = a.) Use a determinant to find all values of k such that the system Ax vector = 0 vector has only the trivial solution.
