Division by 4:
4x ≤ 12
divide both sides by 4:
x ≤ 3

Is the solution to a quadratic inequality in one variable always a compound inequality?
Yes - except in extreme cases. It can be the whole of the Real Numbers: eg x2 > -3 It can be a single point eg x2 ≤ 0 gives x = 0
Explain what happens when both sides of an inequality is multiplied by a negative number give an example to support your answer?
The direction of the inequality is reversed. Note that the if the inequality included "or equals" before, then it will after. 4 < 5 multiplied by -1 gives -4 > -5 5 >= 4 multiplied by -1 gives -5 <= -4
How do you solve the inequality x plus 1 divided by x is greater than or equal to 2?

Why is a linear inequality is usefuln when there are many solutions?
The area in the inequality gives you choices. Like the number of pounds that an elevator can carry is anything less than its maximum.
What is the solution for 3x greater than or equal to 12?
3x ≥ 12. Dividing both sides by 3 gives x ≥ 4
What operation gives the solution to the inequality 4x 12?
An inequality requires an inequality sign, usually "less than", "less-than-or-equal", "greater than", or "greater than or equal". Assuming one of these inequality signs is between the "4x" and the "12", for example: 4x < 12, just divide both sides by 4. Just as when you solve equations, the idea is to isolate the variable on one side.
A substance with equal numbers of H and OH ions is an alkaline solution?
No, only exces of OH- gives you an alkaline solution and exces of H+ gives you an acidic solution. When they are EQUAL then the solution (water) is NEUTRAL, pH= 7.0

What operation gives you the sum of 2 numbers?
The operation is called addition.
What is the solution for 3x greater than or equal to 12?
3x ≥ 12. Dividing both sides by 3 gives x ≥ 4
