simultaneous and quadratic equations.
- INEQUALITIES
- An inequality is an algebraic statement involving the symbols >, <, ≥
or ≤
- If x<2 There are infinitely many values that x could have. It
can be shown on a number line like the one below.
- On a number line if the circle is hollow
it means that its not equal to the
number and if the circle is filled in it
means that it could also be the number
its on.
- An inequality is an algebraic statement involving the symbols >, <, ≥
or ≤
- When there is a pair of equations one is
usually quadratic and the other is linear.
- Equation 1: 2x + y = 7
Equation 2: 3x - y = 8
- 2x + y = 7
3x - y = 8
------------
5x = 15 x =
3
- Now you can put x = 3 in
either of the equations.
Substitute x = 3 into the
equation 2x + y = 7: 6 + y = 7 y
= 1 So the answers are x = 3
and y = 1
- You can also show it in a graph
