Question

Given the matrices A and B shown below, find -B-⅓A​

Answer 1

Explanation:

-B - ⅓A

first multiply all values in the matrix "B" by -1

-1(-2, -10, 2, -5, 0, 6, -8, -5)=

2, 10, -2, 5, 0, -6, 8, 5-your new matrices for "B"

Now multiply all values in the matrix "A" by ⅓

⅓( 0, 12, -15, 3, 15, -3, -9, -6)

0, 4, -5, 1, 5, -1, -3, -2 -your new matrices for "A"

Now subtract the values

2, 10, -2, 5, 0, -6, 8

- 0, 4, -5, 1, 5, -1, -3, -2

___________________

2, 6, 3, 4, -5, -5, 11, 7

Answer 2

Here’s the answer
change the sign of matrix B. Multiply -1/3 by matrix A. Add both the matrices
