Answer:
Lynn gets 3 loafs
Judy gets 9 loafs....
Step-by-step explanation:
Let Lynn gets = x loafs
Judy gets = 3x loafs
Thus the equation becomes:
12 = 3x+x
Add the like terms:
12 = 4x
Divide both sides by 4
12/4=4x/4
x= 3
Lynn gets 3 loafs
Plug the value of x in 3x to find the loafs Judy gets.
3x = 3(3)=9
Judy gets 9 loafs....
The vertex of a quadratic occurs when the velocity, dy/dx=0.
dy/dx=2x+8, so dy/dx=0 only when:
2x+8=0
2x=-8
x=-4, now you find the y coordinate which is:
y(-4)=(-4)^2+8(-4)+12
y(-4)=16-32+12
y(-4)=-4 so the vertex is at the point:
(-4,-4)
