You are driving to a different location and it takes you 90 minutes to get tere if you drive 70 miles per hour. How long will it take you to get there if you drive 50 miles per hour?

—-hours ?

Step-by-step explanation:

The time taken to reach the location = 90 minutes = 1.5 hours

The speed driven = 70 miles per hour

By formula, speed = distance traveled / time taken

70 miles per hour = distance traveled / 1.5 hours

distance traveled in miles = 70 * 1.5 = 105 miles

Speed = 50 miles per hour

Distance = 105 miles

Time taken = ?

speed = distance traveled / time taken

50 = 105 / time taken

time taken in hours = 2.1 hours = 126 minutes

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

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
