A) For 100R, that might mean every week, he is putting 100 dollars away for an interpretation.
B) The Slope represents the time it takes to make 100 dollars, and S represents the total amount of money Tim has.
C) If Tim got to 1250 dollars, it would be 8 for R. So 8 would be the domain and 1250 for the range.

EXPLANATION
The given system of equations is
10x=10
-5x-8y=9
We can rewrite this as:
10x+0y=10
-5x-8y=9
The augmented matrix is the combination of the coefficient matrix and the constant matrix.
The coefficient matrix is
![\left[ { \begin {array} {cc} 10&0\\ - 5& - 8\\ \end {array}} \right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%20%7B%20%5Cbegin%20%7Barray%7D%20%7Bcc%7D%20%2010%260%5C%5C%20-%205%26%20-%208%5C%5C%20%5Cend%20%7Barray%7D%7D%20%20%5Cright%5D%20%20)

Answer:
y= 1/2x+2
Step-by-step explanation:
Plug the slope and coordinates into point slope form y-1=1/2(x+2) and solve.
Let the first number be x
1st number = x
2nd number = x + 2
3rd number = x + 4
4th number = x + 6
5th number = x + 8
x + x + 2 + x + 4 + x + 6 + x + 8 = 120
5x + 20 = 120
5x = 100
x = 20
3rd number = x + 4 = 20 + 4 = 24
Answer: 24
