Extracted text: C. In each of Problems 6 through 15, determine what type of differential equation of order one the following equations is and solve the given equations using the type of differential equation you had given. 9. xy dx + e**dy = 0 10. (2xy – tan y)dx + (x² – xsec²y)dy = 0 11. (y² + 7xy + 16x²)dx + x²dy = 0, when x = 1. v = 1
