To differentiate the quotient of two functions f(x)/g(x) you can use the quotient rule, the formula of which is: (f'(x)*g(x)-f(x)*g'(x))/g²(x)

it is important to remember which...

x = 4.5 

Rearrange the equation, so that like terms are on the same side:

5x - 3x = 2 +7

2x = 9

Then to find x, divide 9 by 2

x = 4...

So I would begin by minusing 5 from both sides and that will give you 3x - 5 ≤ 4x. Then we want to gather our x's onto one side, so I would '-3x' from both sides which leaves you with - 5 ≤ 4x - 3 x, s...

Firstly we must appreciate that if there is an intersection between l and m, this means that there exists a point that occurs on both lines. Therefore if there is an inte...

In order to solve equations of x it is necessary to move all the Xs over to one side and the other numbers over to the other side;

5x - 4 = 3x + 7

As 5x is greater than 3x i...
