Question

Subtract [4 –4 –2] – [4 –3 5].       

\
A. [0 –7 3]  

B. [0 –1 –7]  

C. [0 –1 3]  

D. [0 –1 7]

Answer 1

4-4=0
-4+3=-1
-2-5= -7
b) [0 -1 -7]

Answer 2

The resultant matrix after subtraction is [0 -1 –7]

B is the correct response.

Explanation:

We have to subtract the matrices [4 –4 –2] – [4 –3 5].

Both matrices have same dimension of 1×3. Hence, we can subtract the matrices.

We can subtract the matrices as shown below

[4 –4 –2] – [4 –3 5]

= [4-4 –4-(-3) –2-5]

=[0 -1 –7]

Thus, the resultant matrix after subtraction is [0 -1 –7]

B is the correct response.
