Asked by mav welborn
Ella completed the following work to test the equivalence of two expressions.
5f+3.6
5(1)+3.6
5+3.6
8.6
6f+2.6
6(1)+2.6
6+2.6
8.6
Which is true about the expressions?

The expressions are not equivalent because Ella would get different results when substituting different numbers for f.

The correct response is:
**The expressions are equivalent because Ella got the same result when she substituted one for f.**
This is because both expressions, when evaluated with \( f = 1 \), resulted in \( 8.6 \). However, this does not necessarily mean they are equivalent for all values of \( f \); the equivalence would need to be proven for all possible values of \( f \). Therefore, strictly speaking about the equivalence based on the given test, her substitution demonstrates they yield the same result for that particular case.

I apologize for any confusion in my previous response. Let's clarify the situation regarding the expressions based on Ella's work:
Ella simplified two expressions:
1. \(5f + 3.6\) and evaluated it at \(f = 1\):
- \(5(1) + 3.6 = 5 + 3.6 = 8.6\)
2. \(6f + 2.6\) and evaluated it at \(f = 1\):
- \(6(1) + 2.6 = 6 + 2.6 = 8.6\)
Both evaluations resulted in \(8.6\) when \(f = 1\). However, this does not mean that the two expressions are equivalent for all values of \(f\).
The correct choice based on this analysis should be:
**The expressions are not equivalent because Ella would get different results when substituting different numbers for \(f\).**
Thank you for your patience, and I appreciate the opportunity to correct my response.
