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

There are multiple methods that be applied here to reach a solution, integration by substitution or by applying the basic rules of integration. The first step would be to expand the expression within the ...

= 5a - 4a^2The rules of BODMAS (brackets, Orders, Division, Addition, Subtraction) applies. Times the "a" with "-4a" first, forming 4a squared (4a^2). Then group the "3a" and...

e.g. given x^2 +3x -8 = 0using the quadratic formulayou find x = (-b +- sqrt(b^2 -4ac))/2ayou then find one root using the plus instead of plus minus sign, and the other root using the minus instead of pl...

There are a few steps to this question. Before we can work out our value of X we will have to figure out an equation that links X and Y.Now if X were proportional to Y, then as X got bigger so would Y.We ...
