Find the resulting vector matrix of this matrix multiplication.
1 answer:
Answer:
a = -21 and b = 15
Step-by-step explanation:
It is given a matrix multiplication,
<u>To find the value of a and b
</u>
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
