Math Problem Statement
Which of the following systems of inequalities matches the graph shown?
Solution
To solve this problem, we need to match the shaded region in the graph to the correct system of inequalities from the options provided. Here’s the step-by-step process:
-
Analyze the Graph:
- The shaded region is in the intersection of two constraints defined by lines.
- One line has a negative slope and bounds the region from above, while the other line has a positive slope and bounds the region from below.
-
Examine the Equations:
- The lines have the equations (likely): and .
- The shaded region includes (area below the first line) and (area above the second line).
-
Check the Options:
- From the options:
- and correctly describe the graph's region. Thus, the corresponding choice is the correct system.
- From the options:
The correct answer is .
