If X= [ array ll 1 & 0 0 & 1 array ] and Y= [ array cc 0 & 1 -1 & 0 array ] and B= [ array cc & - & array ] then B equals
Options
- AX +Y
- BX -Y
- C-X +Y
- Dx +y
Correct answer
A. X +Y
Step-by-step solution
Given X = bmatrix 1 & 0 0 & 1 bmatrix and Y = bmatrix 0 & 1 -1 & 0 bmatrix . Calculate X + Y : X = bmatrix & 0 0 & bmatrix Y = bmatrix 0 & - & 0 bmatrix Adding these two matrices: X + Y = bmatrix & 0 0 & bmatrix + bmatrix 0 & - & 0 bmatrix = bmatrix & - & bmatrix This result is identical to the given matrix B . Answer: X +Y
