Answer: The y-value of the vertex is
Step-by-step explanation: we know that
The equation of a vertical parabola into vertex form is equal to
where
(h,k) is the vertex of the parabola
In this problem we have
-----> this a vertical parabola open upward
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side
Rewrite as perfect squares
The vertex is the point
The y-value of the vertex is
YOu have to set a proportion or do this easy method...
5/32= <span>0.15625
the you multiply </span><span>0.15625 by 800 because that is what you want to find out of...
that means the answer is 125
125 ride their bike to school...
hope that helps and you give good feedback

Zack reads faster so he will finish first
Pam= 126/3 = 42/1
Zack= 180/4 =45/1
Now multiply the unit rates by 5 each
Pam= 210/5
Zack= 225/5
It should be the top left because the shaded area is below (or less than) the line -3/4x +1 and greater than the other line
