Answer:
y = (5/27)(x -7)^2 -5/3
Step-by-step explanation:
Use the given points to find the unknowns in the equation.
If the axis of symmetry is x=7, then the equation can be written in the form ...
y = a(x -7)^2 +b
Filling in the two point values, we have two equations:
0 = a(4 -7)^2 +b ⇒ 9a +b = 0
5 = a(1 -7)^2 +b ⇒ 36a +b = 5
__
Subtracting the first equation from the second, we have ...
(36a +b) -(9a +b) = (5) -(0)
27a = 5
a = 5/27
Substituting that value into the first equation gives ...
9(5/27) +b = 0
5/3 +b = 0
b = -5/3
So, the quadratic can be written in vertex form as ...
y = (5/27)(x -7)^2 -5/3

Answer:
![\frac{P-21}{2} =w](https://tex.z-dn.net/?f=%5Cfrac%7BP-21%7D%7B2%7D%20%3Dw)
Step-by-step explanation:
To solve for w use the properties of equality. A property of equality states that if you do the same thing to both sides it is still equal.
First, subtract 21 from both sides
1) P-21=2w
Then, divide both sides by 2
2) (P-21)/2=w
This formula allows you to solve for w by plugging in a P-value.
