Answer:
y = (x-1)^2 - 2
Step-by-step explanation:
The parabola vertex point is always (h, k) in y = (x-h)^2 + k
All you have to do is look at h and k to find your vertex. Since in y = (x-1)^2 -2 has an h of -1 (Which makes it positive 1 when you plug it in) and a k of -2, that means that is your answer.

you can check in your calculator, make sure your calculator is in Degree mode.
Answer:
The total cost for john's meal would be $66.84
Step-by-step explanation:
6.5% of 52.30 = 3.3995
52.30 plus 3.3995 = 55.6995
20% of 55.6995 = 11.14$
55.6995 + 11.14 = $66.84
Divide 12x+3=6 by 3. 12x/3=4x, 3/3=1, 6/3=2.
Basically, to find the best deal for the price, you have to find the price per unit, or in this case, pound.
So just break it down,
Wegmans 30 lb bag- $5- goes to 16 cents a pound
Tops 20 lb bag for $3- goes to 15 cents a pound
and Costco 75 lb bag for $12- goes to 16 cents a pound as well
Then find the rate from the results of cents per pound
I hope this helped in any way, good luck!
