Verify that a div (b+c) != (a divb) +(adivc) for each of the following values of a,b and c. a = (-10),b = 1,c = 1

Consider the matrix A=[[a,b,c],[b,c,a],[c,a,b]] Find Axxadj(A) if a=1 , b=10 , c=100

If a=(2,1,-1), b=(1,-1,0),c=(5,-1,1), then what is the unit vector parallel to a+b-c in the opposite direction?

The inverse of the matrix [(1,0,0),(a,1,0),(b,c,1)] is (A) [(1,0,0),(-a,1,0),(b,c,1)] (B) [(1,0,0),(-a,1,0),(ac,b,1)] (C) [(1,-a,ac-b),(-0,1,-c),(0,0,1)] (D) [(1,0,0),(-a,1,0),(ac-b,-c,1)]

The inverse of the matrix [(1,0,0),(a,1,0),(b,c,1)] is (A) [(1,0,0),(-a,1,0),(b,c,1)] (B) [(1,0,0),(-a,1,0),(ac,b,1)] (C) [(1,-a,ac-b),(-0,1,-c),(0,0,1)] (D) [(1,0,0),(-a,1,0),(ac-b,-c,1)]
