Q7b, Q9a
These are the alternative workings for Q7b by direct differentiation.
Q9a requires you to use chain rule for differentiation with respect to x. Since y is a function of x, it also gets differentiated to dy/dx (implicitly, which arises from the chain rule).
Q9b also requires a similar idea, which I will post next.
