Question

HELP
Find the resulting vector matrix of this matrix multiplication.

Answer 1

-21 and 15

Explanation:

You multiply the two matrices, -1*6+3*-5=-21 and -1*-3+3*4=15

Answer 2

a = -21 and b = 15

Explanation:

It is given a matrix multiplication,

To find the value of a and b

It is given that,

| 6 -5 | * | -1 | = | a |

|-3 4 | | 3 | | b |

We can write,

a = (6 * -1) + (-5 * 3)

= -6 + -15

= -2 1

b = (-3 * -1) + (4 * 3)

= 3 + 12

= 215

Therefore the value of a = -21 and b = 15
