What does the symbol '≤' represent?
lesser than or equal to
How do you express that the price of the house is RM450000 and above in a linear inequality?
x ≥ 450000.
What characterizes a linear inequality in one variable?
An unequal relationship between a number and a variable with a power of 1.
What does a linear inequality typically have in terms of solutions?
More than one possible solution.
How do you solve the inequality 16 - 5x ≤ -4?
Rearranging gives x ≥ 4.
What result do you get when solving the simultaneous inequalities 8x + 5 ≥ 5x - 13 and 3x - 4 > 9x + 20?
The solution is -6 ≤ x < -4.
Which operation would you perform to isolate 'x' in the inequality 8x + 5 ≥ 5x - 13?
Subtract 5x and 5 from both sides.
In the inequality 3x - 4 > 9x + 20, what is the first step to solve for 'x'?
Add 4 to both sides.
What is the final inequality that describes the solution set for the simultaneous equations given in the examples?
-6 ≤ x < -4.
