Maths - Unit 7 - Linear Inequalities - Form 1

What is the symbol for 'at least' in linear inequalities?

≥ (greater than or equal to)

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.
