Understanding Inequalities

The video tutorial from MooMoo Math and Science explains how to solve inequalities. It covers three examples, demonstrating the steps to isolate variables and find solutions. The video emphasizes understanding the process of solving inequalities and checking which numbers satisfy the conditions. It concludes with a motivational message about kindness.

What is the first step in solving the inequality 4M - 2 ≤ 30?

• Add 2 to both sides

• Subtract 2 from both sides

• Divide both sides by 4

• Multiply both sides by 4

After solving the inequality 4M - 2 ≤ 30, which of the following values satisfy the inequality?

• 9 and 10

• 5 and 7

• 7 and 9

• 8 and 6

What operation is performed after subtracting 4 from both sides in the inequality R/2 + 4 ≥ -1?

• Subtract 2

• Add 4

• Divide by 2

• Multiply by 2

Which of the following numbers satisfy the inequality R ≥ -10?

• -11 and -12

• -9 and -8

• -10 and -11

• -10 and -9

What is the result of dividing both sides by -4 in the inequality 4 - 4N ≤ 16?

• N ≤ 3

• N ≥ -3

• N ≤ -3

• N ≥ 3

Which of the following values satisfy the inequality N ≤ -3?

• 4 and 5

• 2 and 3

• -2 and -3

• -4 and -5

Why does the number 24 not satisfy the inequality 4 - 4N ≤ 16?

• Because 24 is not a valid number

• Because 24 is greater than 16

• Because 24 is less than 16

• Because 24 is equal to 16

What happens when you subtract a negative number in an inequality?

• It becomes zero

• It remains negative

• It becomes a negative subtraction

• It becomes a positive addition

In the context of inequalities, what does it mean when two negatives are added?

• The result is undefined

• The result is zero

• The result is negative

• The result is positive

What is the importance of checking solutions in inequalities?

• To find more solutions

• To verify the solution satisfies the inequality

• To ensure the solution is incorrect

• To simplify the inequality further
