Hello! Any help is appreciated.
v= <-9,2> is transformed using the transformation matrix A = [-4 1
-1 2]
What is the resulting vector? Show all of your work.
[ -9 2 ] [ -4 1 ]
[ -1 2 ]
The resulting matrix will be a ( 1 x 2) * ( 2 x 2) = 1 x 2
-9 (-4) + 2(-1) = 36 - 2 = 34
-9(1) + 2(2) = -9 + 4 = -5
The resulting matrix (vector) is
[ 34 -5 ]
