Answer:
s = -1
Step-by-step explanation:
-7/3(12s + 24) + 14 = -14
-28s - 56 + 14 = -14
-28s - 42 = -14
-28s = 28
s = -1

Answer:
![Rateofchange=\frac{f(x_2)-f(x_1)}{x_2-x_1}](https://tex.z-dn.net/?f=Rateofchange%3D%5Cfrac%7Bf%28x_2%29-f%28x_1%29%7D%7Bx_2-x_1%7D)
where x₁ and x₂ are values in the interval [x,y] respectively
Step-by-step explanation:
Well, first to determine the average rate of change of a function, you should have the interval of the values of x for the function.
So lets assume you have a function;
![f(x)=x^3-4x](https://tex.z-dn.net/?f=f%28x%29%3Dx%5E3-4x)
And the interval as [1,3]
Then the average rate of change for the function f(x) will be;
![=\frac{f(x_2)-f(x_1)}{x_2-x_1}](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%28x_2%29-f%28x_1%29%7D%7Bx_2-x_1%7D)
where x₁ and x₂ are the interval coordinates x,y respectively. In this case x₁=1 and x₂=3
To find the average rate of change in this example will be;
![=\frac{f(x_2)-f(x_1)}{x_2-x_1} \\\\=f(x_2)=f(3)=3^3-4(3)=27-12=15\\\\=f(x_1)=f(1)=1^3-4(1)=1-4=-3\\\\\\=x_2-x_1=3-1=2\\\\\\=\frac{15--3}{2} \\\\=\frac{18}{2} =9](https://tex.z-dn.net/?f=%3D%5Cfrac%7Bf%28x_2%29-f%28x_1%29%7D%7Bx_2-x_1%7D%20%5C%5C%5C%5C%3Df%28x_2%29%3Df%283%29%3D3%5E3-4%283%29%3D27-12%3D15%5C%5C%5C%5C%3Df%28x_1%29%3Df%281%29%3D1%5E3-4%281%29%3D1-4%3D-3%5C%5C%5C%5C%5C%5C%3Dx_2-x_1%3D3-1%3D2%5C%5C%5C%5C%5C%5C%3D%5Cfrac%7B15--3%7D%7B2%7D%20%5C%5C%5C%5C%3D%5Cfrac%7B18%7D%7B2%7D%20%3D9)
