Shaun read 60 pages in 34 h.

what is the unit rate representing the number of pages shaun can read in 1 h?

The number of pages Shaun can read 1.765 pages in an hour

Solution:

Given that, Shaun reads 60 pages in 34 hours.  

To find: The unit rate representing the number of pages Shaun can read in 1 hr.

Assume the unit to be found out is x.  

To find x, we have to divide the terms,  

34 hours = 60 pages

So, the number of pages in an hour is 1.765

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
