What is the BEST description of an inequality?
- a comparison of two numbers
- the set of numbers greater than 0
- the set of numbers less than 0
- a pair of integers that are the same distance from 0
An inequality compares the value of two numbers.
Numbers greater than 0 are positive.
Numbers less than 0 are negative.
This is a description of opposite integers.
How does a number line help you write an inequality?
- You can plot the integers along a number line and then see which is further to the right. This is the greater integer.
- You can plot the integers along a number line and then see which is further to the right. This is the smaller integer.
- The greater integer, which is the larger number in an inequality, is always positive.
- The greater number, which is the larger number in an inequality, is always negative.
The value of integers increases as you move to the right along a number line.
The value of integers increases as you move to the right along a number line.
When comparing two negative integers, one will be greater.
Sometimes the greater number is negative, but sometimes the greater number is positive.
Which symbol makes the inequality TRUE?
9 _____ −10
- <
- >
- =
- ≤
The integer 9 is further to the right on the number line than the integer −10.
The integer 9 is greater than the −10 because 9 is further to the right on the number line than the integer −10.
The integer 9 is not equal to the integer −10.
The integer 9 is larger than the integer −10.
Antonio and Ben are playing basketball. Antonio is 75 inches tall, and Ben is 77 inches tall.
Which inequality compares the heights of Antonio and Ben?
- 75 ≥ 77
- 75 > 77
- \( |75| \) > \( |77| \)
- 77 > 75
The integer 75 is further to the left than 77 on the number line.
The integer 75 is further to the left than 77 on the number line.
The integer 75 is further to the left than 77 on the number line. This is true regardless of the absolute value symbols.
The integer 77 is further to the right on the number line than 75.
The school dance has 329 students attend. After an hour, 90 of the students leave.
Which compares the integers \( |329| \) and \( |-90| \)?
- \( |-90| \gt |329| \)
- \( |-90| \le |329| \)
- \( |-90| \ge |329| \)
- \( |90| \ge |-329| \)
The value of \( |-90| \) = 90. This number is not greater than 329.
The value of \( |-90| \) = 90 and \( |329| \) = 329. The integer 90 is further to the left on the number line than 329.
The value of \( |-90| \) = 90. This number is not greater than or equal to 329.
Make sure the numbers you are using match the problem.
