Understanding the Inequality

Anja represents the inequality $\frac{4-g}{8} \leq -15$ with the phrase "the quotient of the difference of 4 and a number and 8 is at least -15." This phrase is an attempt to describe the given inequality, but it contains an error. To understand Anja's error, we need to break down the inequality and analyze each component.

Breaking Down the Inequality

The given inequality is $\frac{4-g}{8} \leq -15$. To represent this inequality as a phrase, we need to consider the following components:

• The quotient: The quotient is the result of dividing one number by another. In this case, the quotient is $\frac{4-g}{8}$.
• The difference: The difference is the result of subtracting one number from another. In this case, the difference is $4-g$.
• The inequality: The inequality states that the quotient is less than or equal to -15.

Anja's Error

Anja's phrase states "the quotient of the difference of 4 and a number and 8 is at least -15." This phrase contains two errors:

• Incorrect order of operations: Anja's phrase states that the difference of 4 and a number is being divided by 8, but the correct order of operations is to subtract the number from 4 and then divide the result by 8.
• Incorrect representation of the inequality: Anja's phrase states that the quotient is "at least -15," but the correct representation of the inequality is that the quotient is less than or equal to -15.

Correct Representation of the Inequality

A correct representation of the inequality would be: "the quotient of the difference of a number and 4 and 8 is less than or equal to -15." This phrase accurately represents the given inequality and avoids the errors present in Anja's phrase.

Conclusion

Anja's error in representing the inequality is due to an incorrect order of operations and an incorrect representation of the inequality. By understanding the components of the inequality and breaking it down, we can identify the errors and provide a correct representation of the inequality.

Common Inequalities and Their Representations

Here are some common inequalities and their representations:

• Linear inequality: $ax + b \leq c$ can be represented as "the sum of a number and b is less than or equal to c."
• Quadratic inequality: $ax^2 + bx + c \leq 0$ can be represented as "the sum of a number squared and a number and c is less than or equal to 0."
• Absolute value inequality: $|x| \leq c$ can be represented as "the absolute value of a number is less than or equal to c."

Conclusion

In conclusion, representing inequalities accurately is crucial in mathematics. By understanding the components of the inequality and breaking it down, we can identify errors and provide a correct representation of the inequality. By following tips for representing inequalities, we can avoid common mistakes and ensure that our representations are clear and concise.
