Question

HELP Find the resulting vector matrix of this matrix multiplication.

Answer 1

Answer:

a = -21 and b = 15

Step-by-step 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
