State, with reason, whether the following is true or false. A, B and C are matrices of order 2 × 2.
A – B = B – A
Solve the following system of linear equation using matrix method:
`1/x + 1/y +1/z = 9`
`2/x + 5/y+7/z = 52`
`2/x+1/y-1/z=0`
Classify the following matrix :
`|(1 , 1),(0,9)|`
If A = `|(1,9,4),(5 , 0 , 3)|` find A'
If A = `|(1,3),(3,2)|` and B = `|(-2,3),(-4,1)|` find AB
If A = `|(1,3),(3,2)|` and B = `|(-2 , 3),(-4 , 1)|` find BA
Let A = `|(3 , 2),(0 ,5)|` and B = `|(1 ,0),(1 ,2)|` , find (i) (A + B)(A - B) (ii) A2 - B2 . Is (i) equal to (ii) ?
`[(2, -1),(5, 1)]`
[2 3 – 7]
`[(0, 0, 0),(0, 0, 0)]`
