Answer:
A) 6,737,400 (I think)
B) The average rate of 2008 to 2016
Step-by-step explanation:
A)
(6,420,000 + 3,060,000 + 7,610,000 + 7,930,000 + 8,667,000)/5 = 6,737,400
(Here we take the whole amount burned and divide it by 5 which is the number of years presented)
B)
2000 to 2008 :
6,420,000 + 3,060,000 + 7,610,000 = 17,090,000
Whereas 2008 to 2016 :
7,610,000 + 7,930,000 + 8,667,000 = 24,207,000
Therefore the answer is :
The average rate of 2008 to 2016
8
Since y is a solution of the homogeneus system then satisfies Ay=0.
Since z is a solution of the system Ax=b then satisfies Az=b.
Now, we will show that A(y+z)=b.
Observe that A(y+z)=Ay+Az by properties of the product of matrices.
By hypotesis Ay=0 and Az=b.
Then A(y+z)=Ay+Az=0+b=b.
Then A(y+z)=b, this show that y+z is a solution of the system Ax=b.
