We can see that x=y-1 and therefore can sub this in our first equation, to give us 3(y-1)+2y=22. If we expand the brackets we than have 3y-3+2y=22 which can be tidied up to give 5y-3=22. If we add 3 to bo...
The setting of The Bloody Chamber bares way to a suitable 'atmosphere' for the exploration of the speaker's unconscious mind. The speaker moves away from the busy musical life of her home in Paris, to the...
Firstly you should work out the first derivative of the equation y= After differentiating the equation, sub the x value of the point P into the first derivative. This should give you the gradient of the e...
If you already know the text, I would begin by taking a past paper and going through all relevant questions, summarising how you would answer each one. Set a time limit - you’ll have about 30 minu...
This is because the atomic mass of an element is the sum of protons and neutrons. While the proton number is specific for an element, the neutron number can vary for different isotopes of the element. The...
