Capitolo 1, Problema 77
Rewrite each statement with > so that it uses < instead. Rewrite each statement with < so that it uses >. -9 < 4
Guida verificata passo dopo passo1
Identify the inequality symbol in the given statement. Here, the statement is \(-9 < 4\), which uses the less than symbol $<$.
Recall that the inequality \(a < b\) means that \(a\) is less than \(b\). To rewrite this using the greater than symbol $>$, we reverse the inequality and swap the two sides.
Swap the two sides of the inequality: the left side becomes \(4\) and the right side becomes \(-9\).
Change the inequality symbol from $<$ to $>$ to maintain the truth of the statement after swapping.
Write the new inequality as \(4 > -9\), which is the equivalent statement using the greater than symbol.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.
Inequality Symbols and Their Meaning
Inequality symbols like < (less than) and > (greater than) compare two values to show their relative size. Understanding what each symbol represents is essential to correctly interpret and rewrite inequalities.

Reversing Inequalities
When rewriting inequalities by switching the direction of the symbol, the inequality sign must be reversed. For example, if the original statement is a < b, rewriting it with > requires changing it to b > a.

Properties of Inequalities with Negative Numbers
Working with negative numbers in inequalities requires careful attention, as their order on the number line is reversed compared to positive numbers. Recognizing how negative values relate helps avoid mistakes when rewriting inequalities.
