Test for symmetry about the x-axis: Replace y with (-y). Simplfy the equation. If the resulting equation is equivalent to the original equation then the graph is symmetrical about the x-axis. Example: Use the test for symmetry about the x-axis to determine if the graph of y - 5x2 = 4 is symmetric about the x-axis.

I didn't fully understand the question but this is the best I can do! Hope this helps! :D
Answer:
60%
Step-by-step explanation:
It’s simple
He needs to do 60, he has done 36
Percentage = (36/60) * 100
= 60%
120-36 = 84 <==== what he has left
84/120×100% = percentage of what he has left
70% = percentage aka answer.
I think the answer is option e mn
