The correct Answer is:
To solve the linear inequalities \(2x + y \geq 4\), \(x + y \leq 3\), and \(2x - 3y \leq 6\), we will follow these steps: ### Step 1: Convert inequalities to equations We first convert each inequality into an equation to find the boundary lines. 1. **First inequality**: \(2x + y = 4\) 2. **Second inequality**: \(x + y = 3\) 3. **Third inequality**: \(2x - 3y = 6\) ### Step 2: Find intercepts for each equation We will find the x-intercept and y-intercept for each equation. 1. **For \(2x + y = 4\)**: - **x-intercept**: Set \(y = 0\): \[ 2x + 0 = 4 \implies x = 2 \quad \text{(Point: (2, 0))} \] - **y-intercept**: Set \(x = 0\): \[ 2(0) + y = 4 \implies y = 4 \quad \text{(Point: (0, 4))} \] 2. **For \(x + y = 3\)**: - **x-intercept**: Set \(y = 0\): \[ x + 0 = 3 \implies x = 3 \quad \text{(Point: (3, 0))} \] - **y-intercept**: Set \(x = 0\): \[ 0 + y = 3 \implies y = 3 \quad \text{(Point: (0, 3))} \] 3. **For \(2x - 3y = 6\)**: - **x-intercept**: Set \(y = 0\): \[ 2x - 3(0) = 6 \implies 2x = 6 \implies x = 3 \quad \text{(Point: (3, 0))} \] - **y-intercept**: Set \(x = 0\): \[ 2(0) - 3y = 6 \implies -3y = 6 \implies y = -2 \quad \text{(Point: (0, -2))} \] ### Step 3: Plot the lines on a graph Now we plot the points on a graph and draw the lines: - For \(2x + y = 4\): Points (2, 0) and (0, 4) - For \(x + y = 3\): Points (3, 0) and (0, 3) - For \(2x - 3y = 6\): Points (3, 0) and (0, -2) ### Step 4: Determine the regions for each inequality Next, we need to determine which side of each line satisfies the inequality: 1. **For \(2x + y \geq 4\)**: - Choose a test point, e.g., (0, 0): \[ 2(0) + 0 \geq 4 \implies 0 \geq 4 \quad \text{(False)} \] - The solution lies on the side opposite to the origin. 2. **For \(x + y \leq 3\)**: - Choose a test point, e.g., (0, 0): \[ 0 + 0 \leq 3 \quad \text{(True)} \] - The solution lies on the side including the origin. 3. **For \(2x - 3y \leq 6\)**: - Choose a test point, e.g., (0, 0): \[ 2(0) - 3(0) \leq 6 \quad \text{(True)} \] - The solution lies on the side including the origin. ### Step 5: Identify the feasible region The feasible region is where all the shaded areas from the inequalities overlap. This region will be bounded by the lines we plotted. ### Step 6: Conclusion The solution to the system of inequalities is the region where all three inequalities are satisfied. This region can be shaded on the graph.
