You are trying to decide if you should use Company A or Company B to get a ride to a concert. A graph of their costs is shown below. Analyze the system as graphed here and choose EACH true statement below.

Question 4 options:

Company A charges $5 for zero miles.

At exactly 2 miles, the two companies will cost the same.

Company A charges $3.50 per mile.

If I'm going more than two miles, Company A is a better value.

Company B charges $4 for every single mile you ride.

If I'm going less than two miles, Company B will charge me more than Company A.

step-by-step explanation:

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

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

a)(x-2)^2+(y-1)^2=9
