### Finding the Area of an Enclosed Region Using Integration

To find the area of the region enclosed by the equations \( y = 4.75x \) and \( x = 8.5 - y^2 \), follow these steps. The graph provides a visual guide for the enclosed region.

#### Graph Explanation:
The graph displays a region bounded by two curves:
1. \( y = 4.75x \), which is a straight line.
2. \( x = 8.5 - y^2 \), which is a parabola opening to the left.

#### Steps to Find the Enclosed Area:

1. **Use Horizontal Strips to Find the Area**:
   Integrate with respect to \( y \) to find the area of the region.

2. **Find the \( y \)-coordinates of Intersection**:
   Determine the points where the line \( y = 4.75x \) intersects the parabola \( x = 8.5 - y^2 \).

   Solve the system of equations:

   \[
   y = 4.75x 
   \]

   and 

   \[
   x = 8.5 - y^2 
   \]

   Substitute \( y \) from the first equation into the second equation:

   \[
   x = 8.5 - (4.75x)^2 
   \]

   Simplify to find the \( y \)-values at the points of intersection. These values will be the limits of integration.

   - Lower limit \( c = \) [Enter Value]
   - Upper limit \( d = \) [Enter Value]

3. **Set Up the Integral**:
   To find the area of the enclosed region from \( c \) to \( d \):

   \[
   \int_{c}^{d} g(y) \, dy 
   \]

   Here, \( g(y) \) is the difference of the functions representing the curves, rearranged in terms of \( y \) if necessary.

4. **Evaluate the Integral**:
   Solve the definite integral to find the area.

   - [Set Up Integral]
   - Evaluate the definite integral to find the area \( \text{Area} = \) [Enter Value]

### Example Calculation
(For simplicity, assume example values for the coordinates and corresponding integral setup).

1. Determine the intersection points:
   - Solve for \( y \
