2. (1 point) In problems below, (a) identify the independent 2. variable and the dependent variable of each equation (use 't" dx x2 - 5y for the independent variable if an independent variable is not 3. +6 dy given explicitly): (b) give the order of each differential equation dx2 dx (enter 'I' for first order, '2" for second order and so on; do not -4. dy dx - 10ry include the quotes); and (c) state whether the equation is linear or nonlinear. If your answer to (c) is nonlinear, make sure that 5. dy dx +9x y = 9 you can explain why this is true.
