The correct Answer is:
To solve the given linear inequalities and specify the bounded region, we will follow these steps: ### Step 1: Convert Inequalities to Equalities We start by converting each inequality into an equality to find the boundary lines: 1. \(2x + y = 2\) 2. \(x - y = 1\) 3. \(x + 2y = 8\) 4. \(x = 0\) (y-axis) 5. \(y = 0\) (x-axis) ### Step 2: Find Intercepts of Each Line Next, we find the intercepts for each line to plot them on the graph. 1. **For \(2x + y = 2\)**: - When \(x = 0\), \(y = 2\) (point: (0, 2)) - When \(y = 0\), \(x = 1\) (point: (1, 0)) 2. **For \(x - y = 1\)**: - When \(x = 0\), \(y = -1\) (point: (0, -1)) - When \(y = 0\), \(x = 1\) (point: (1, 0)) 3. **For \(x + 2y = 8\)**: - When \(x = 0\), \(y = 4\) (point: (0, 4)) - When \(y = 0\), \(x = 8\) (point: (8, 0)) ### Step 3: Plot the Lines Now, we will plot the lines on a graph using the points found above. 1. **Line for \(2x + y = 2\)**: Plot points (0, 2) and (1, 0) and draw the line. 2. **Line for \(x - y = 1\)**: Plot points (0, -1) and (1, 0) and draw the line. 3. **Line for \(x + 2y = 8\)**: Plot points (0, 4) and (4, 2) and draw the line. 4. **Lines for \(x = 0\) and \(y = 0\)**: These are the axes. ### Step 4: Determine the Feasible Region Next, we need to determine which side of each line satisfies the inequality. 1. **For \(2x + y \geq 2\)**: Test the origin (0, 0): - \(2(0) + 0 \geq 2\) → False. So, the solution lies on the right side of the line. 2. **For \(x - y \leq 1\)**: Test the origin (0, 0): - \(0 - 0 \leq 1\) → True. So, the solution lies below the line. 3. **For \(x + 2y \leq 8\)**: Test the origin (0, 0): - \(0 + 2(0) \leq 8\) → True. So, the solution lies below the line. 4. **For \(x \geq 0\) and \(y \geq 0\)**: This restricts us to the first quadrant. ### Step 5: Identify the Bounded Region The bounded region is where all the shaded areas from the inequalities overlap. This will be a polygon formed by the intersection points of the lines. ### Step 6: Find Intersection Points To find the vertices of the bounded region, we need to solve the equations pairwise: 1. **Intersection of \(2x + y = 2\) and \(x - y = 1\)**: - Solve the system: \[ 2x + y = 2 \quad (1) \] \[ x - y = 1 \quad (2) \] - From (2), \(y = x - 1\). Substitute into (1): \[ 2x + (x - 1) = 2 \implies 3x - 1 = 2 \implies 3x = 3 \implies x = 1 \] \[ y = 1 - 1 = 0 \implies (1, 0) \] 2. **Intersection of \(x - y = 1\) and \(x + 2y = 8\)**: - Solve: \[ x - y = 1 \quad (3) \] \[ x + 2y = 8 \quad (4) \] - From (3), \(x = y + 1\). Substitute into (4): \[ (y + 1) + 2y = 8 \implies 3y + 1 = 8 \implies 3y = 7 \implies y = \frac{7}{3} \] \[ x = \frac{7}{3} + 1 = \frac{10}{3} \implies \left(\frac{10}{3}, \frac{7}{3}\right) \] 3. **Intersection of \(2x + y = 2\) and \(x + 2y = 8\)**: - Solve: \[ 2x + y = 2 \quad (5) \] \[ x + 2y = 8 \quad (6) \] - From (5), \(y = 2 - 2x\). Substitute into (6): \[ x + 2(2 - 2x) = 8 \implies x + 4 - 4x = 8 \implies -3x = 4 \implies x = -\frac{4}{3} \text{ (not in the first quadrant)} \] 4. **Intersection of \(x + 2y = 8\) and \(y = 0\)**: - Substitute \(y = 0\) into \(x + 2(0) = 8\): \[ x = 8 \implies (8, 0) \] ### Conclusion The vertices of the bounded region are: 1. (1, 0) 2. (0, 4) 3. (0, 2) 4. \(\left(\frac{10}{3}, \frac{7}{3}\right)\) The bounded region is the area enclosed by these points in the first quadrant.
