Understanding Inequalities

What does the prefix 'in' in 'inequality' signify?

• Not equal

• Less than

• Greater than

• Equal

How is 'C is less than negative four' represented as an inequality?

• C <= -4

• C > -4

• C < -4

• C = -4

What does 'at most 16' imply in an inequality?

• Equal to 16

• Less than 16

• Greater than 16

• Less than or equal to 16

What is a solution set in the context of inequalities?

• A single solution that makes the inequality true

• A graph representing the inequality

• All possible solutions that make the inequality true

• The maximum value in an inequality

If 'X is less than 6', which of the following is NOT a solution?

• 6

• 0

• 4

• 5

Is 'X = 8' a solution to 'X + 1 > 7'?

• Yes

• No

• Insufficient information

• Only if X is less than 8

Why is 'Y = 4' not a solution to '7Y < 27'?

• Because the inequality only accepts negative numbers

• Because 7*4 is 28, which is not less than 27

• Because 7*4 is 27, which is equal to 27

• Because Y cannot be a whole number

How is 'X is greater than 2' graphed on a number line?

• With an open dot at 2 and an arrow pointing right

• With a closed dot at 2 and an arrow pointing right

• With an open dot at 2 and an arrow pointing left

• With a closed dot at 2 and an arrow pointing left

What does a closed dot on a number line signify?

• The number is not included in the solution set

• The inequality is not valid

• The number is included in the solution set

• The solution set is empty

In graphing 'Y is less than or equal to 4', which direction does the arrow point?

• Both directions, as all numbers are included

• To the left, indicating numbers less than 4

• To the right, indicating numbers greater than 4

• No arrow is drawn for inequalities
