Question

Please solve and explain the following.

Using the system (picture), find the minimum value and maximum value using the given f(x,y) function.

The image contains a set of inequalities and a function that may describe a region in a coordinate plane and a linear function. Here is the transcription and explanation:

**Inequalities:**

1. \( 0 \leq y \leq 5 \)
   - This inequality indicates that \( y \) is bounded between 0 and 5.

2. \( y \leq -x + 5 \)
   - This represents a line with a negative slope (-1), intersecting the y-axis at 5. The region of interest is below or on this line.

3. \( y \leq x + 5 \)
   - This represents a line with a positive slope (1), also intersecting the y-axis at 5. The region of interest is below or on this line.

**Function:**

- \( f(x, y) = 8x - 3y \)
  - This is a linear function of two variables, \( x \) and \( y \). The function describes a plane in three-dimensional space where the value of the function depends on the inputs \( x \) and \( y \).

**Explanation:**

The inequalities together form a bounded region on the xy-plane. The function \( f(x, y) = 8x - 3y \) could be evaluated over this bounded region to find maximum or minimum values within the constraints. This type of problem is often seen in linear programming and optimization contexts.
