We first rearrange the inequality to obtain

4x²-5x+1>0

To plot any graph, you need to find out where the curve cuts the x and y-axis, and where it's stationary points are, aswell as what type of stationary point you have.

Here are the steps:

a) The first part of this question is asking us to find points, (x,y), such that    x = -8. By taking the equation and substituting in x = -8, we should find values, y, such that the points given are (-8,...

2x - 6y = 18

4x + 3y = 6

First, make either the x or y the same value by multiplying the equations. Let's choose x.

2x - 6y = 18      x2

4x + 3y = 6     ...

For any sequence where there is a common difference (it increases or decreases with the same amount, n, each time) you can find the nth term using the formula: dn+(a-d)&q...
