Answer 1

Answer:

C

Step-by-step explanation:

Subtract corresponding components in the second matrix from those in the first matrix, that is

$\left[\begin{array}{ccc}-6-(-5)&-4-5\\6-(-4)&0-(-1)\\6-6&4-(-4)\end{array}\right]$

= $\left[\begin{array}{ccc}-6+5&-4-5\\6+4&0+1\\6-6&4+4\end{array}\right]$

= $\left[\begin{array}{ccc}-1&-9\\10&1\\0&8\end{array}\right]$ → C
