Determine whether S is a basis for R₃. S = {(5, 4, 3), (0, 4, 3), (0, 0,3)} OS is a basis for R₃. O S is not a basis for R₃. If S is a basis for R₃, then write u = (15, 8, 15) as a linear combination of the vectors in S. (Use 51, 52, and 53, respectively, as the vectors in S. If not possible, enter IMPOSSIBLE.) u = 3(5,4,3) – (0,4,3) +3(0,0,3) Your answer cannot be understood or graded. More Information
