B. y=x+2x-2 is the correct quadratic function
The two equations for the set up are:
x+y=23 where x is the number of dimes and y is the number of nickles
10x+5y=185
Now you solve by elimination and substitution.
Multiply your first equation by -5 and add the two equations together
-5x-5y=-115
+10x+5y=185
-------------------
5x=70
x=14
Substitute that into your original equation:
14+y=23
y=9
So you have 14 dimes and 9 nickles.
Hope this helps
