Best ResponseYou've already chosen the best response.1it is inconsistent if the first row is a multiple of the second or the third row. From the last entry (the 0 and 2 ), the first row can't be a multiple of the second row.

Best ResponseYou've already chosen the best response.1Is this a homogenous equation AX=0 or AX=b. In the second case what is our b here?

Best ResponseYou've already chosen the best response.0Ax=b All values of k make the matrix inconsistent because the last row has a 'b' value of 0. The first two cannot equal zero. Am I correct?

Best ResponseYou've already chosen the best response.1sok, so to make it inconsistent then k=6. Because we will have 6x6y=0. If we divide that by 3 we have 2x2y=0. Meanwhile the second row tells us that 2x2y=2 (and it can't be 0 and 2 at the same time)

Best ResponseYou've already chosen the best response.1It has no solution, so it is inconsistent

Best ResponseYou've already chosen the best response.0right. but it has no solution no mater the case for k.
