Answer:
<em>The estimated sales were $260 million</em>
Step-by-step explanation:
Assume the endpoints of a segment are (x1,y1) and (x2,y2).
The midpoint (xm,ym) is calculated as follows:
![\displaystyle x_m=\frac{x_1+x_2}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x_m%3D%5Cfrac%7Bx_1%2Bx_2%7D%7B2%7D)
![\displaystyle y_m=\frac{y_1+y_2}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y_m%3D%5Cfrac%7By_1%2By_2%7D%7B2%7D)
The sales ov Cars, Inc. were (2008,240 million) and (2010,280 million). We need to use the midpoint to estimate the sales in 2009:
![\displaystyle x_m=\frac{2008+2010}{2}=2009](https://tex.z-dn.net/?f=%5Cdisplaystyle%20x_m%3D%5Cfrac%7B2008%2B2010%7D%7B2%7D%3D2009)
![\displaystyle y_m=\frac{240+280}{2}=260](https://tex.z-dn.net/?f=%5Cdisplaystyle%20y_m%3D%5Cfrac%7B240%2B280%7D%7B2%7D%3D260)
The estimated sales were $260 million
Step-by-step explanation:
I'll do 2.
Alright,Alex let say we have factored a quadratic into two binomial, for example
![(5x + 3)(6x - 4)](https://tex.z-dn.net/?f=%285x%20%2B%203%29%286x%20-%204%29)
If we set both of those equal to zero
![(5x + 3)(6x + 4) = 0](https://tex.z-dn.net/?f=%285x%20%2B%203%29%286x%20%2B%204%29%20%3D%200)
We can used the zero product property in this case to find the roots of the quadratic equation.
This means that
![if \: ab = 0 \: then \: a = 0 \: and \: b = 0](https://tex.z-dn.net/?f=if%20%20%5C%3A%20ab%20%3D%200%20%5C%3A%20then%20%5C%3A%20a%20%3D%200%20%5C%3A%20and%20%5C%3A%20b%20%3D%200)
This means we set each binomal equal to zero to find it root.
![5x + 3 = 0](https://tex.z-dn.net/?f=5x%20%2B%203%20%3D%200)
![5x = - 3](https://tex.z-dn.net/?f=5x%20%3D%20%20-%203)
![x = - \frac{3}{5}](https://tex.z-dn.net/?f=x%20%3D%20%20-%20%20%5Cfrac%7B3%7D%7B5%7D%20)
![6x + 4 = 0](https://tex.z-dn.net/?f=6x%20%2B%204%20%3D%200)
![6x = - 4](https://tex.z-dn.net/?f=6x%20%3D%20%20-%204)
![x = - \frac{2}{3}](https://tex.z-dn.net/?f=x%20%3D%20%20-%20%20%5Cfrac%7B2%7D%7B3%7D%20)
So our roots are negative 3/5 and negative 2/3 using zero product property
So you have
1. Low money account balance
2. Negative degrees
3. Possible points in a game.
