Answer:
y=(x-5)^2-4
Step-by-step explanation:
this is because the -4 drops it below the line and then x-5^2 stays where it is so mainly the minus in the domian and range and the -4 moves it over
Answer:
16,800 dollars
Step-by-step explanation:
1. find 20 percent of 21,000= 4,200
2. subtract 4,200 from 21,000
21,000
-4,200
16,800 dollars
Let x represent the number originally signed up.
.. 360/x -6 = 360/(x +3)
.. 360*(x +3) -6x(x +3) = 360x . . . . . multiply by the product of denominators
.. 360x +1080 -6x^2 -18x = 360x
.. x^2 +3x -180 = 0
.. (x +15)(x -12) = 0
Solutions are x = {-15, 12}
12 members went on the trip.
_____
The problem wording does not make clear whether the original number (12) or the number suggested by the bus company (15) went on the trip. It would be most reasonable for 15 to go, if the troop had people who were willing.

Answer:
The zero of the equation represents the maximum height attained by the shot put.
Step-by-step explanation:
William is competing in the shot put event at a track meet. The quadratic expression that models the vertical height of the shot from the ground is
H = 
We can find the zeroes of these two equations.
For that put H = 0.
= 0
(-2x + 5)(x + 1) = 0
x= -1 or x = 2.5
x= -1 is neglected as it is not practical.
x = 2.5 is the maximum height attained by the shot put.
The zero of the equation represents the maximum height attained by the shot put.
