Helppp pls for the 2 people willing to help .

Step-by-step explanation: I honestly am too lazy to solve but I will tell you what to do. For number 1-5 you need the amount (a) divided by the Tax/Tip/%off/Discount(d). Whatever that number is (t), you subtract that from a to get the total cost which is (c) So in other words - a-d=t a-t=c UWU

Then onto the next ones. Number 6: First you do 11/2800. Thats the 11%. Next you get 67,530 divide that by that last number you got. Then multiply that by 2800. Then there is your answer

Okay so next one Number 7: Same thing as the other one actually -v-

Next answer mate! Number 8: 3400 x4 + (3400/3.5) x 4= You tell me that ;)

We almost don Number 9: 20460 x 5 + (20460/5.5) x 5= Hhehehehe last one mate

We actually at the last one. Its been fun helping you! :) Number 10: 35000/7 then whatever that is times 5. I enjoyed going back in my little kid brain tohelp you :)

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
