Graph the given system and determine the vertices of the overlapping region. Substituting these vertices into the equation will help you find the minimum value.
Graph:
Vertices:(8,0),(2,3) Minimum:8 at (8,0)
Practice makes perfect
Our first step in finding the maximum value of the given equation is to graph the given system and determine the vertices of the overlapping region. Substituting these vertices into the equation, we will find the minimum value.
⎩⎪⎪⎨⎪⎪⎧x+2y≥8x≥2y≥0(I)(II)(III)
Inequality I
To graph an inequality, we first determine its boundary line. By changing the inequality symbol to an equals sign, the boundary line can be determined.
Inequality: BoundaryLine: x+2y≥8x+2y=8
Since the boundary line is not in slope-intercept form, we will rewrite it in slope-intercept form.
