Does (2,0) work as a solution to the systems of equations to lines 3x+y=6 and 3x-y=6
1 answer:
Answer:
Yes
Step-by-step explanation:
To see if (2,0) works as a solution to the systems of equations, we plug in the values of x and y and simplify. If the results are equal, then (2,0) is a solution.
3x + y = 6:
- (2,0) is a solution to this equation.
3x - y = 6:
- (2,0) is a solution to this equation.
Therefore, the answer is yes, it does work as a solution.

1 -49,350 0.909091 -44,863.64
2 -49,350 0.826446 -40,785.12
3 -49,350 0.751315 -37,077.39
4 -49,350 <u> 0.683013 </u> <u>-33,706.71 </u>
Total $ 3.169865 $ -156,432.86
Therefore, Net Present value = present value of the annual cash flow - initial investment.
= 156,432.86 - 280,000
= $ 436,432.86 (negative)
Now the EAC or the Equivalent Annual Cost for System A :

6 -47,030 <u> 0.564474 </u> <u> -26,547.21 </u>
Total $ 4.355261 $ -204,827.91
Net Present Value = Present Value of annual cash inflows – Initial Investment
= -$ 564,827.91 (negative)
EAC for system B:
