Answer:
%55
Step-by-step explanation:
divide both values by 2, multiply by 10 to give you a percentage
d
cannot be a or c cause it has a negative sign in front of it causing it to reflect over y axis. Cannot be B cause it doesn't have two coefficients with X. I also graphed it.
12/43 = 27.90%
1. 12/43 = x/100
2. x= 100(12/43)
3. x= 27.90%
7980
900+80+7000=7980
