For which of the following ordered pairs \[(\mu ,\delta )\], the system of linear equations |
\[x+2y+3z=1\] |
\[3x+4y+5z=\mu \] |
\[4x+4y+4z=\delta \] |
Is inconsistent? |
A) \[(4,3)\]
B) \[(4,\,6)\]
C) \[(3,4)\]
D) \[(1,0)\]
Correct Answer: A
Solution :
[a] For inconsistent system we need \[\Delta =0\] and at least one of \[\Delta x,\,\,\Delta y\,\Delta z\ne 0\]You need to login to perform this action.
