There's a bit of lack of context but I think the question is just asking what variables to put in for Lucy and Howard. There seems to be no need to answer any math problem.
I suggest using the variables x and y or l for Lucy and h for Howard. Remember to use lowercase letters.
Answer:
37°
Step-by-step explanation:
too tired to give an explanation, just trust it
By equating both quadratic equations, Brian can determine the point of intersection of both equations. Upon graphing he was able to identify that both share the same vertex but of opposite opening. Based on this, he can say that both equations are equations of parabolas with same vertex but open on different directions.
Hi do you mind showing your on the side or something thank you
Your answers are fine.
1) Transitive property if a = b and b = c, then a = c. Replace with your letters and is is done.
2) Symmetric property of equality.
If a = b, then b = a.
