Answer:
X=[24,,-33]
Step-by-step explanation:
The given equation is :
We multiply through by 3 to get:
Solve for x to get:
The entries are: A=[-12 -3] B= [-12 10]
Let X=[a,b]
We substitute the entries to get:
[a,b]=[-12,-3]-3[-12,10]
We simplify the Right Hand Side to get:
[a,b]=[-12,-3]-[-36,30]
We simplify further to get:
[a,b]=[-12--36,-3-30]
This implies that:
[a,b]=[24,-33]
Hence, X=[24,-33]

Answer: 
are the cube numbers 
Step-by-step explanation:
Hopefully you are able to clearly see the steps I have taken toward solving this problem in the attachment. In case you have trouble understanding what a reciprocal is, the reciprocal of a number is simply the number flipped. So, if you are given 1/2 and asked what the reciprocal is, it would be 2/1, or just 2. That being said, if you are given a whole number, simply remember that a whole number is ALWAYS equal to itself over one. So, in this case, the "sum of a number and its reciprocal" would be n +
1/n
