Answer 1

Answer:

Can each vector in R4 be written as a linear combination of the columns of the matrix A? Do the columns of A span R4 -60 -15 12 0 2 -3 10 Can each vector in R4 be written as a linear combination of the columns of the matrix A? Select the correct choice below and fill in the answer box to complete your choice (Type an integer or decimal for each matrix element.) d A. No, because the reduced row echelon form of A is 11. O B. Yes, because the reduced row echelon form of A is l-l- Do the columns of A span R4? O A. Yes, because A does not have a pivot position in every row. O B. Yes, because all b in Rm can be wrtten as a linear combination of the columns of A. ° C. No, because not all b in Rrm can be written as a linear combination of the columns of A O D. No, because A has a pivot position in every row.
