Answer :
To find the resulting vector matrix of the given matrix multiplication, we perform the following steps:
1. Identify the given matrix [tex]\(A\)[/tex] and vector [tex]\(B\)[/tex]:
[tex]\[ A = \begin{bmatrix} 6 & -5 \\ -3 & 4 \\ \end{bmatrix} \][/tex]
[tex]\[ B = \begin{bmatrix} -1 \\ 3 \\ \end{bmatrix} \][/tex]
2. Compute the first element [tex]\(a\)[/tex] of the resulting vector by multiplying the first row of matrix [tex]\(A\)[/tex] with vector [tex]\(B\)[/tex]:
[tex]\[ a = (6 \times -1) + (-5 \times 3) \][/tex]
[tex]\[ a = -6 - 15 \][/tex]
[tex]\[ a = -21 \][/tex]
3. Compute the second element [tex]\(b\)[/tex] of the resulting vector by multiplying the second row of matrix [tex]\(A\)[/tex] with vector [tex]\(B\)[/tex]:
[tex]\[ b = (-3 \times -1) + (4 \times 3) \][/tex]
[tex]\[ b = 3 + 12 \][/tex]
[tex]\[ b = 15 \][/tex]
So, the resulting vector matrix of the multiplication is:
[tex]\[ \begin{bmatrix} -21 \\ 15 \\ \end{bmatrix} \][/tex]
Therefore, [tex]\(a = -21\)[/tex] and [tex]\(b = 15\)[/tex].
