Answer:
I think its linear so I dont know 100% but I think it's a sorry if I'm wrong
(Kevin) y= k-6 - k minus six
(Melanie) y= 2(k-6) - two times k minus six
K, only got that far... sorry
When it says per month, it means to multiply. In this case, the expression would be;
25x+50
So however many months Fatima has spent at the gym, you would multiply that times 25 and add the initiation fee. Hope this helps.
No profit means P(x)=0: x³-4x²+3x-12=0
factor by regrouping: x²(x-4)+3(x-4)=0
take out (x-4): (x-4)(x²+3)=0
x=4 or x²=-3
x² is not a negative number, so x=4 is the only answer.
