5th Term is a+18b=442nd term is a+ 6b=8subtract the two equations from eachother to get 12b=36 rearrange so that b=36/12=3 substitute b=3 into any of the above equations to get a; a=8-(6x3) = -10 so a=-10...

i) x² + y²- 6x - 4y + 4 = 0 x²- 6x + y² - 4y + 4 = 0 group the terms together x²- 6x = (x - 3)² - 9 factorise the x ter...

To find the quotient and remainder of an algebraic division we use a technique similar to long division at GCSE. I think the best and easiest way to learn this method is to go through an example. See the ...

First we need to list what we know from the text. Bob's speed : 13,48 mph and 6hour a day. The distance is 392,5 miles. How do we get the number of hours? Distance/Speed = 392,5/13,48 = 29,1172~ 29,12hour...

step 1: re-arrange the function in a nicer wayx = (y + 4)/44x = y + 4y = 4x - 4step 2: draw the graphthis is a stright line going through y axis at -4 and x axis at 1, with gradient of 4
