The correct Answer is:
To solve the system of linear inequalities given by \(2x + y \geq 6\) and \(3x + 4y \leq 12\), we will follow these steps: ### Step 1: Convert inequalities to equations First, we convert the inequalities into equations to find the boundary lines. 1. For the first inequality \(2x + y = 6\). 2. For the second inequality \(3x + 4y = 12\). ### Step 2: Find intercepts for the first equation To graph the line \(2x + y = 6\), we can find the x-intercept and y-intercept. - **X-intercept**: Set \(y = 0\): \[ 2x + 0 = 6 \implies x = 3 \quad \text{(Point: (3, 0))} \] - **Y-intercept**: Set \(x = 0\): \[ 2(0) + y = 6 \implies y = 6 \quad \text{(Point: (0, 6))} \] ### Step 3: Find intercepts for the second equation Next, we find the intercepts for the line \(3x + 4y = 12\). - **X-intercept**: Set \(y = 0\): \[ 3x + 4(0) = 12 \implies x = 4 \quad \text{(Point: (4, 0))} \] - **Y-intercept**: Set \(x = 0\): \[ 3(0) + 4y = 12 \implies y = 3 \quad \text{(Point: (0, 3))} \] ### Step 4: Graph the lines Now we can plot the lines on a graph: 1. The line \(2x + y = 6\) passes through points (3, 0) and (0, 6). 2. The line \(3x + 4y = 12\) passes through points (4, 0) and (0, 3). ### Step 5: Determine the region for each inequality - For \(2x + y \geq 6\): The region above the line is included (shaded). - For \(3x + 4y \leq 12\): The region below the line is included (shaded). ### Step 6: Test a point to find the feasible region To find the feasible region, we can test a point that is not on either line. A common choice is the origin (0, 0). - For \(2x + y \geq 6\): \[ 2(0) + 0 \geq 6 \quad \text{(False)} \] - For \(3x + 4y \leq 12\): \[ 3(0) + 4(0) \leq 12 \quad \text{(True)} \] Since the first inequality is false at the origin, the feasible region does not include the origin. Thus, we shade the area that does not include the origin. ### Step 7: Identify the feasible region The feasible region is the area where the shaded regions of both inequalities overlap. ### Conclusion The solution to the system of inequalities \(2x + y \geq 6\) and \(3x + 4y \leq 12\) is the area of intersection of the two shaded regions, which is bounded by the lines and does not include the origin. ---
