To find the coordinates of the point, we have to solve the equations simultaneously. To do this, we need the same number for the coefficient of x or y in each equation. Arbitrarily, we will chose to match...

We are trying to solve 27^-2/3. Firstly, using the index rule a^xy= (a^x)^y, this can be rewritten as (27^1/3)^-2. Lets tackle the value inside ...

First we need to draw a velocity-time diagram, which has time on the x-axis, or bottom, and velocity on the y-axis, or left.The ball begins from a stop, so we can draw a dot at (0,0). It accelerates until...

If Fred and Julie share £60 in a 5:7 ratio, Fred will get 5/12ths of the money and Julie will get 7/12ths of the money. All together there will be 12 parts of the money because 5 + 7 = 12So, you need to d...
