    Separating variables for an equation?

    Did I solve these correctly? Separating variables for an equation?-capture5.jpgFor the first one I couldn't seperate I or III, so I think that's right. For the second I'm pretty sure I separated them right but I'm not totally confident about it.

    On #6, you still have a function of x on the left-hand side.

    Oh I didn't notice that. Hm, would it be not separable then? Because dividing e^-x from both sides does give me any of those answers, right?

    If you divide both sides by e^{-x} (or multiply by e^x), you get answer #2.

    Okay. Thanks! I didn't know that was how you divided by e^-x. Good to know!
