hkus10 Posted January 21, 2011 Share Posted January 21, 2011 1) Is the matrix [upper row 3 0 and lower row 0 2] a linear combination of the matrices [upper row 1 0 and lower row 0 1] and [upper row 1 0 and lower row 0 0]? Justify your answer. Is it I just have to add the two matrices to see if they are equal the matrix, [upper row 3 0 and lower row 0 2]? 2) Show that the linear system obtained by adding a multiple of an equation in (2) to another equation is equivalent to (2). How to show that? Thanks! Link to comment Share on other sites More sharing options...
Shadow Posted February 10, 2011 Share Posted February 10, 2011 As for 1), I confess I haven't watched the video myself, but this might help you. I don't understand question 2), but that might just be a consequence of the fact that I know practically nothing of matrices. Just though I'd pitch in the video and hope it helps a bit.

Justify your answer. Is it I just have to add the two matrices to see if they are equal the matrix, [upper row 3 0 and lower row 0 2]? no Go review what is meant by a generalinear combination. Show that the linear system obtained by adding a multiple of an equation in (2) to another equation is equivalent to (2). How to show that? Thanks! What is 2) ? This doesn't make sense.
