Answer:
The average rate of change(A(x)) of a function f(x) from a to b as;
![A(x) = \frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=A%28x%29%20%3D%20%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
Given the function: ![f(x) = 480(0.3)^x](https://tex.z-dn.net/?f=f%28x%29%20%3D%20480%280.3%29%5Ex)
For x =1 ,
![f(x) = 480(0.3)^1 = 480\cdot 0.3 = 144](https://tex.z-dn.net/?f=f%28x%29%20%3D%20480%280.3%29%5E1%20%3D%20480%5Ccdot%200.3%20%3D%20144)
and for x=5
![f(x) =480(0.3)^5 = 480 \cdot 0.00243= 1.1664](https://tex.z-dn.net/?f=f%28x%29%20%3D480%280.3%29%5E5%20%3D%20480%20%5Ccdot%200.00243%3D%201.1664)
then;
the average rate of change of a function A(x)=
or
![A(x) =\frac{1.1664-144}{4}= \frac{-142.8336}{4}= -35.7084](https://tex.z-dn.net/?f=A%28x%29%20%3D%5Cfrac%7B1.1664-144%7D%7B4%7D%3D%20%5Cfrac%7B-142.8336%7D%7B4%7D%3D%20-35.7084)
Therefore, the average rate of change of the given function from x=1 to x=5 is; -35.7084
Answer:
y ≤![\frac{7}{4}x - 5](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B4%7Dx%20-%205)
Step-by-step explanation:
We are to put the linear inequality;
7x - 4y ≥ 20
in slope intercept form.
We can rearrange the inequality as;
-4y ≥ - 7x + 20
Dividing throughout by -4 we get;
y ≤
- 5
Note that the inequality sign '≥' changes to '≤' since we divided all through with a negative number.
