C. In each of Problems 6 through 11, determine what type of differential equation of order one (Variable Separable, Homogenous, Exact or Linear) the following equations is and solve the given equations using the type of differential equation you had given. 6. (xy' + y - x)dx + x(xy + 1)dy = 0, when x = 2, y = 2 7. (16x + 5y)dx + (3x + y)dy = 0, when x = 1,y = -3 8. (y2 + 7xy + 16x2)dx + x2dy = 0, when x = 1,y = 1 9. x(x2 + 1)y' + 2y = (x2 + 1)3, whenx = 1,y = 1 10. (cos 2y - 3x2y? )dx + (cos 2y - 2x sin 2y - 2x3y)dy = 0 11. (3x2 - 2y? )y' = 2xy, when x = 0,y = -1
