Chapter 2: Problem 75
List five integer solutions of each inequality. See Sections 1.2 through 1.4. $$ |y|>-10 $$
Short Answer
Expert verified
Any integer satisfies the inequality because \(|y|\) is always greater than \(-10\).
Step by step solution
01
Understanding the Absolute Value
The inequality \(|y| > -10\) is presented. It's important to recall that the absolute value, denoted by \(|y|\), represents the magnitude of \(y\) without regard to its sign. Absolute values are always non-negative (zero or positive).
02
Interpreting the Inequality
The inequality \(|y| > -10\) is interpreted. Since absolute values are always non-negative, they are always greater than \(-10\). This means that any integer value of \(y\) satisfies \(|y| > -10\).
03
Listing Possible Solutions
Given that any integer satisfies the inequality, we can select any five integers as solutions. Common integers such as \(y = -2, 0, 5, 10, 20\) will suffice as they all satisfy the condition.

Key Concepts
These are the key concepts you need to understand to accurately answer the question.
Integer Solutions
When working with inequalities like \(|y| > -10\), finding integer solutions involves picking numbers from the set of integers. Integers include all whole numbers, both positive and negative, as well as zero. Here are a few properties to remember about integers:
- They do not include fractions or decimals.
- They are a countable set, stretching infinitely in both the positive and negative directions.
Inequalities
Inequalities offer a way to express relationships between numbers that are not necessarily equal. An inequality like \(|y| > -10\) tells us there is a range of possible solutions rather than a single number. Here's what to know about inequalities:
- The inequality sign \(>\) means 'greater than'.
- Inequalities can show with \(>\) or \(<\) and their 'or equal to' counterparts, \(\geq\) and \(\leq\).
Non-Negative Values
Non-negative values are numbers that are equal to or greater than zero. Absolute values, such as \(|y|\), fall under this category because they measure distance from zero, a concept that cannot be negative. Here’s what you should keep in mind about non-negative values:
- They include all positive numbers and zero.
- The only values excluded are negative numbers.
Magnitude of a Number
The magnitude of a number is essentially its absolute value without focusing on sign. What does this mean?
- It quantifies how far a number is from zero on the number line.
- For instance, the magnitudes of \(-7\) and \(7\) are both \(7\).
