Shaded Region Inequalities Ba12B4
1. The problem asks to find the three inequalities that define the shaded triangular region bounded by the lines shown on the graph.
2. From the graph description, the boundaries are:
- A vertical line at $x=5$
- A horizontal line at $y=3$
- A slanting line passing through points $(1,1)$ and $(5,7)$
3. The inequalities must describe the region inside the triangle formed by these lines.
4. For the vertical line $x=5$, the shaded region is to the left, so the inequality is:
$$x \leq 5$$
5. For the horizontal line $y=3$, the shaded region is above, so the inequality is:
$$y \geq 3$$
6. For the slanting line through $(1,1)$ and $(5,7)$, first find its equation:
The slope $m = \frac{7-1}{5-1} = \frac{6}{4} = \frac{3}{2}$
Equation in point-slope form:
$$y - 1 = \frac{3}{2}(x - 1)$$
Simplify:
$$y = \frac{3}{2}x - \frac{3}{2} + 1 = \frac{3}{2}x - \frac{1}{2}$$
7. The shaded region is below this line, so the inequality is:
$$y \leq \frac{3}{2}x - \frac{1}{2}$$
8. Therefore, the three inequalities defining the shaded region are:
$$x \leq 5$$
$$y \geq 3$$
$$y \leq \frac{3}{2}x - \frac{1}{2}$$
9. The inequalities you wrote, $5 \leq 6$, $3 \leq 2$, and $5 \geq 2$, are not related to the graph or the shaded region and are incorrect.
Final answer:
$$x \leq 5, \quad y \geq 3, \quad y \leq \frac{3}{2}x - \frac{1}{2}$$
