As we can see in both results, it would take them
(4 hours) for the prices to be equaled.
Answer:
Step-by-step explanation:
To find this, graphing would be easiest. Graph each function and see which one has an axis of symmetry at x=3
Answer:
16.6 :)
Step-by-step explanation:
To complete the square:
1) Move the "non-x" term to the right.
It's already there.
2) Divide the equation by the coefficient of x^2.
It's already done. Coefficient of x^2 is 1.
3) <span>• take the coefficient of X
this is -2
• divide it by 2
-2 / 2 =-1
• square that number
-1^2 = 1
• then add it to both sides of the equation.
x^2 -2x = 24
x^2 -2x +1 = 25
</span>
<span>4) take the square root of both sides of the equation (remember that each square root has TWO solutions).
</span>
<span>Taking the square root of
x^2 -2x +1 = 25
equals
(x -1) = 5 AND
</span>
<span>(x -1) = -5
So, x = 6 and
x = -4
