Equations And Inequalities Flashcards
What are the two ways of solving Linesr Simultaneous Equations
By using elimination and substitution
Simultaneous equations with one linear and one quadratic equation can have how many pairs of solutions
They can have up to two pairs of solution but they must be paired correctly
What do the solutions of a pair of simultaneous equations represent
They represent the points of intersection of their graphs
What is the solution of an inequality
It is the set of all real number x that make the inequality true
How do you solve a quadratic inequality
Rearrange so that the right-hand side of the inequality is 0
Solve the corresponding quadratic equation to find the critical values
Sketch the graph of the quadratic functions
Use the sketch to find the required set of values
What does y < f(x) represent
The points on the coordinate grid below the curve y = f(x)
What does y > f(x) represent
The points on the coordinate grid above the curve y = f(x)
