Lizzie joins a fitness club that has a membership fee of $20 Plus $15 per month. Rations club has a fee of $40 and charges $10 per month
Write a system of equations to model this situation
And how many months will the two clubs cost the same what is the cost
If you only planted on joining a fitness club for six months over the winter which club is the better deal

1st club- 15x +20 Rations-  10x +40  After 4 months the clubs cost the same of $80. The Rations would be a better choice for 6 months.

Step-by-step explanation: 15 would be x because it is per month and you would add a $20 fee each month. For Rations 10 would be x because it is per month and you would add a $40 fee. If you put 15x +20 = 10x  +40 (first subtract 10x from both sides and then you would get 5x then subtract 40 -20 and get 20, divide that by 5x and x = 4). 15 times 6 + 20 = 110, while 10 times 6 + 40 = 100 so that means rations would be the better choice

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
