-12 4 8 0 Let u = -8 and A: o 2 4 . ls u in the subset of R3 spanned by the columns of A? Why or why not? 13 3110 Select the correct choice below and ll in the answer box to complete your choice. (Type an integer or decimal tor each matrix element.) '11:} A- Yes, multiplying A by the vector writes u as a linear combination of the columns of A. {3' B- No, the reduced echelon form of the augmented matrix is , which is an inconsistent system. Find a basis for the eigenspace corresponding to the eigenvalue. 1 -6 A: ,k=8 -3 6 A basis for the eigenspace corresponding to 2' = 8 is D. (Type a vector or list of vectors. Type an integer or simplied fraction for each matrix element. Use a comma to separate answers as needed.)
