Answer:
its B
Step-by-step explanation:
The answer for that is .. 17?
Answer:
28
Step-by-step explanation:
40% 6th graders of 70 total = 28 6th graders
40% 6th graders + 20% 7th graders = 60%
100% - 60% = 40% 8th graders
40% are 8th graders therefore the answer is 28
ANSWER
A. No because f(c)=-30
EXPLANATION
The given polynomial is
![f(x) =2x^3-9x^2+13x-6](https://tex.z-dn.net/?f=f%28x%29%20%3D2x%5E3-9x%5E2%2B13x-6)
If x+1 is a factor , then f(-1) must evaluate to zero.
![f( - 1) =2( - 1)^3-9( - 1)^2+13( - 1)-6](https://tex.z-dn.net/?f=f%28%20-%201%29%20%3D2%28%20-%201%29%5E3-9%28%20-%201%29%5E2%2B13%28%20-%201%29-6)
![f( - 1) =2( - 1)-9( 1)+13( - 1)-6](https://tex.z-dn.net/?f=f%28%20-%201%29%20%3D2%28%20-%201%29-9%28%201%29%2B13%28%20-%201%29-6)
![f( - 1) = - 2-9 - 13-6](https://tex.z-dn.net/?f=f%28%20-%201%29%20%3D%20-%202-9%20-%2013-6)
![f( - 1) = -11 - 19](https://tex.z-dn.net/?f=f%28%20-%201%29%20%3D%20-11%20-%2019)
![f( - 1) = - 30](https://tex.z-dn.net/?f=f%28%20-%201%29%20%3D%20-%2030)
Since f(-1) is not equal to zero, x+1 is not a factor of
![f(x) =2x^3-9x^2+13x-6](https://tex.z-dn.net/?f=f%28x%29%20%3D2x%5E3-9x%5E2%2B13x-6)
$20-$14.56=$5.44
The mechanic would get $5.44 back as change.
