Answer:
1
Step-by-step explanation:
The function f(x)=x+6*2 can be rewritten as f(x)=x+12
The average rate of change on the function f on [a,b] interval is the ratio of the changes
:
![\bigtriangleup=\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cbigtriangleup%3D%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
We determine our substitute our interval values in the function:
![f(9)=9+12=21\\\\f(4)=4+12=16\\\\\bigtriangleup=\frac{21-16}{9-4}\\\\=1](https://tex.z-dn.net/?f=f%289%29%3D9%2B12%3D21%5C%5C%5C%5Cf%284%29%3D4%2B12%3D16%5C%5C%5C%5C%5Cbigtriangleup%3D%5Cfrac%7B21-16%7D%7B9-4%7D%5C%5C%5C%5C%3D1)
Hence, the average rate of change is 1
Answer:
N = 15 & x = 3.2
Step-by-step explanation:
divide 6 by 2 to get 1/5, which is 3. then you multiply 3 by 5 to get the answer.
sixteen-thirds is equal to 5 1/3, which you can divide by 7 to get one-seventh, which is 0.8. Then you can multiply that by 4 to get 3.2.
The third one because it says 4 of 7 and the rest which is 3 eat a school meal
So the ratio is 4:3
7(3)^2 - 3(3) - 6 = 7*3*3 - 3*3 - 6 = 63 - 9 - 6 = 48
