Inequalities
Solve linear, quadratic and rational inequalities; represent solutions on number lines and using set notation
What you'll learn
- 1
Inequalities compare two things — like saying 'x is bigger than y' or 'x is smaller than y'. The signs < and > are like hungry crocodiles that always eat the bigger number! 🐊
- 2
Which sign would you put here: 7 ___ 4? The crocodile eats the bigger number.
- 3
On a number line, numbers get bigger as you go right. So x > 2 means x is anywhere to the right of 2.
- 4
Which numbers satisfy x < 5? Let's find them together.
- 5
Drag the point to show where x > 3 is on the number line.
- 6
Which of these numbers satisfies x ≥ 2? (≥ means 'greater than or equal to')
- 7
If x ≤ -1, which of these is a possible value for x?
