Answer:
Option d. (-2,-5)
Step-by-step explanation:
we know that
The equation of a vertical parabola in vertex form is equal to
where
a is a coefficient
(h,k) is the vertex of the parabola
In this problem we have
This is the equation of a vertical parabola open up
The vertex is minimum
Convert the equation in vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
-----> equation in vertex form
therefore
The vertex is (-2,-5)
Hey there!
What you do is find how much was taken off and add that to the price
60*.2= 12
12 was taken off of the original price
Now add:
60+12= 72
So the regular price was $72
4P2 * 2P1 * 3P2
you want to use permuations instead of combinations because order matters.
12*2*6=144
