The inverse of the matrix [(1,1,1),(1,0,2),(3,1,1)] is a) (1)/(4)[(-2,0,2),(5,-1,2),(1,-1,-2)] b) (1)/(4)[(-2,0,2),(5,-2,-1),(1,2,-1)] c) (1)/(4)[(-2,0,2),(2,5,-1),(-2,-1,1)] d) (1)/(4)[(-2,0,2),(5,-1,1),(1,-2,-1)]

If [(2,1),(3,2)] A[(-3,2),(5,-3)]=[(1,0),(0,1)] then a is equal to (A) [(0,1),(1,1)] (B) [(1,0),(1,1)] (C) [(1,1),(1,0)] (D) [(1,1),(0,1)]

If A^(-1) =[(3,-1,1),(-15,6,-5),(5,-2,2)] and B = [(1,2,-2), (-1,3,0), (0,-2,1)] find (AB)^(-1)

If A^(-1) =[(3,-1,1),(-15,6,-5),(5,-2,2)] and B = [(1,2,-2), (-1,3,0), (0,-2,1)] find (AB)^(-1)

3(5a-7)-2(9a-11)=4(8-13-1)

If A=[(2),(0),(1)],B-[(4,-2,5)],C=[(0,1),(1,0),(-1,1)] then ABC=

If f(x)=x^(2)+4x-5andA=[(1,2),(4,-3)] , then f(A) is equal to a) [(0,-4),(8,8)] b) [(2,1),(2,0)] c) [(1,1),(1,0)] d) [(8,4),(8,0)]

Using the distance formula, show that the given points are collinear. (i) (1, -1), (5, 2) and (9, 5) (ii) (6, 9), (0, 1) and (-6, -7) (iii) (-1, -1), (2, 3) and (8, 11) (iv) (-2, 5), (0, 1) and (2, -3).
