Inequality Region
1. **State the problem:** We want to understand the system of inequalities:
$$y - x < 2$$
$$2y + 3x \leq 12$$
$$x \geq 0$$
and describe the solution region they define.
2. **Rewrite each inequality for clarity:**
- From $$y - x < 2$$, add $$x$$ to both sides to get
$$y < x + 2$$
This means the region below the line $$y = x + 2$$, not including the line since it's strict inequality.
- From $$2y + 3x \leq 12$$, isolate $$y$$:
$$2y \leq 12 - 3x$$
$$y \leq \frac{12 - 3x}{2} = 6 - \frac{3}{2}x$$
This is the region below or on the line $$y = 6 - \frac{3}{2}x$$.
- The third inequality $$x \geq 0$$ represents all points on or to the right of the $$y$$-axis.
3. **Interpret the combined solution region:**
- The feasible region satisfies all three:
- Below the line $$y = x + 2$$ (strictly less than)
- Below or on the line $$y = 6 - \frac{3}{2}x$$
- To the right of or on the $$y$$-axis
This means the solution set is the intersection of these three regions in the coordinate plane.
4. **Final answer:**
The solution region is all points $$ (x,y) $$ such that
$$x \geq 0, \quad y < x + 2, \quad y \leq 6 - \frac{3}{2}x.$$
