So your equation is y = x² - 20x + 15. what you'll want to do is complete the square, so take half of 20 and square it. 20/2 = 10. 10² = 100. add 100 to both sides. and simplify x²-20x+100+15 to (x²-10)²+15. now subtract 100 from both sides to get y alone. this leaves you with y = (x²-10)-85. that's your vertex form.

Answer:
The monthly payment is $241.76.
Step-by-step explanation:
Given : Suppose you take out a car loan for $9999 for 4 years at a 7.5% interest rate.
To find : What is your monthly payment ?
Solution :
The formula to find monthly payment is
Discount factor is
Substitute in the formula,
where, A is the amount A=$9999
r is the rate =7.5%=0.075
time t=4 years
Time in months
Substitute all the values in the formula,
Therefore, the monthly payment is $241.76.
The correct answer is B
multiply both sides by 12 to get the answer:
R = 12
