Numbers & Their Opposites Review

How can you determine which of two negative numbers is greater?

• The number further from zero is greater.

• The number closer to zero is greater.

• Both numbers are equal.

• The larger absolute value is greater.

What does it mean if an inequality is false?

• An inequality is true when the relationship between the two values holds true.

• An inequality is false when the relationship between the two values does not hold true.

• An inequality is false when both values are equal.

• An inequality is true when one value is greater than the other.

What is the absolute value of -6?

• 4

• 6

• -6

• 0

How do you express a location above sea level?

• As negative numbers

• As positive numbers

• As fractions

• As percentages

How do you represent a number greater than zero on a number line?

• Numbers greater than zero are located to the left of zero on a number line.

• Numbers greater than zero are located to the right of zero on a number line.

• Numbers greater than zero are located at zero on a number line.

• Numbers greater than zero are located below zero on a number line.

What is the relationship between absolute values and inequalities?

• Absolute values can be used in inequalities to compare distances from zero. For example, if |x| < 5, x is within 5 units of zero.

• Absolute values are always greater than zero and cannot be used in inequalities.

• Absolute values indicate the maximum value of a variable in an inequality.

• Absolute values can only be used in equations, not inequalities.

What does it mean for a fishing line to be at -45 feet?

• It means the fishing line is 45 feet below the water surface, represented as a negative value.

• It means the fishing line is 45 feet above the water surface, represented as a positive value.

• It means the fishing line is at the water surface level, represented as zero feet.

• It means the fishing line is 45 feet away from the shore, represented as a distance measurement.

What is the relationship between depth and absolute value?

• Depth below a reference point is represented as a positive number.

• Depth below a reference point is represented as a negative number, and the absolute value indicates how far below the surface it is.

• Depth and absolute value are unrelated concepts.

• Absolute value is always a negative number regardless of depth.

If Lee is at -5 feet and Kelsey is at +8 feet, who is further from the starting point of 0?

• Lee is further from the starting point of 0.

• Kelsey is further from the starting point of 0 because +8 is greater than -5.

• Both are at the same distance from the starting point.

• Neither is further from the starting point of 0.

What is the significance of the number line in understanding positive and negative numbers?

• The number line visually represents the order of numbers, with positive numbers to the right of zero and negative numbers to the left.

• The number line is used to measure distances between points in space.

• The number line only represents whole numbers and does not include fractions or decimals.

• The number line is primarily used for plotting graphs in algebra.
