Nicholas borrowed $250 from his parents to buy a video game system. he has agreed to pay them back $15 each week. which equation represents the amount of money nicholas still owes his parents, p, after w weeks?

p = 250 - 15(w)

Step-by-step explanation:

Original amount: 250

No of weeks to return money:  w

Amount to pay each week: 15  

Amount that he has paid back: 15 × w  (When we subtract this term from the total we will get the answer)

So after w weeks he owes his parents :

p = 250 - 15(w)

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
