Step-by-step explanation:
To create a real-life system of equations for this problem, let's consider the cash flows as revenues and costs for a business over the course of five years.
Let:
- \( R_0, R_1, R_2, R_3, R_4 \) represent the revenues in years 0, 1, 2, 3, and 4, respectively.
- \( C_0, C_1, C_2, C_3, C_4 \) represent the costs in years 0, 1, 2, 3, and 4, respectively.
We can represent the net cash flow (revenues minus costs) for each year with the following system of equations:
1. Net cash flow for year 0:
\[ R_0 - C_0 \]
2. Net cash flow for year 1:
\[ R_1 - C_1 \]
3. Net cash flow for year 2:
\[ R_2 - C_2 \]
4. Net cash flow for year 3:
\[ R_3 - C_3 \]
5. Net cash flow for year 4:
\[ R_4 - C_4 \]
Let's represent these equations on a graph. Since there are five variables, we won't be able to graph the entire system in a traditional 2D coordinate system. Instead, we can graph each equation separately on a 2D graph with the x-axis representing the years and the y-axis representing the net cash flow. Each equation will be represented as a line on the graph. However, the x-coordinate for each point will be the year, not a numerical value.
