The important thing here is to try and find the bottom bracket in the top bracket ie the numerator

Notice that (3x-3) can be divided by 3 and therefore (3x-3) can be written as 3 multiplied by (x-1...

8x + 3. When you differentiate you must take each term separately. For the first term (4x^2) you must times the coefficent of x (4) by the power (2) and subtract one from the power. Giving an answer of 8 ...

First, we can temporarily make this an equation rather than an inequality to make it easier to solve. We replace the “<” with an equals sign “=”. The inequality now becomes an equality: 2x - 10 = 6 - 2...

This is an easy one as long as you remember the important equation y = mx + c. I can't express how important it is for you to learn that equation.

Step one: find y. Do this by taking 3x away from b...

The mean is the total of the numbers divided by how many numbers there are. So to find the mean of six, we need to add three numbers together, divide those three numbers by three and get six. This sounds ...
