Equation 1: 4x-y=3  Equation 2: 3x-2y=1

We have to find a common multiple between 4 and 3 so that both equations have the same first value. This means that we can get rid of the x by subtracting th...

dy/dx = 3x^2

The first step is to multiply out the brackets so the function is in a form that can be integrated. X x X² = X³ then X x 2 is simply 2X. So we are left with X³ + 2X. Both ...

First we need to know how many days are still remaining before the end of January. In this case it would be 10 since 31-21=10. We know that 8th of February  is the 8th day of the month, so in total betwee...

1. Draw sketch of line 2. Find gradient using m=(y₂ - y₁)/(x₂ - x₁)= 5--4/2--1=9-3=3 3. Choose one of the points and call it (a,b). I'll pick (2,5) because t...
