Unless I've made any daft mistakes in my hurry they should be OK. (Let me know if you find any please!)
Hope you like what you see!!

P.S. These are my solutions and are not the definitive solutions. There are often alternative ways to solve a question and different ways of leaving an answer. For example, straight line equations can be arranged a few ways. If your solutions don't exactly match these that doesn't necessarily mean that you are wrong or won't gain full/partial marks.
