<span>f(x) = x^2 – 12x + 20</span>
Let 'x' represent the monthly membership fee for the gyp.
Since 1 year = 12 month for 1 year Alyson will pay 12x dollars.
But if she pay in advance 12x dollars she will receive $50 discount and pay $514:

x = $47
The monthly membership fee is $47.
hope it helps

2) 2/3
Step-by-step explanation:
1) f(x)=x+4
*subtract 4 to both sides
x=-4
2) f(x)=3x-2
*add 2 to both sides then divide by 3*
x= 2/3
hope this helps :)
