The linear formula for the sequence whose terms represent the percentage of americans who smoke n years after 2014 is:

<h3>What is a linear function?</h3>
A linear function is modeled by:

In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and for a time-dependent function, can also be interpreted as the initial value.
In this problem:
- The percentage of smokers in 2014 was 16.7%, hence the initial value is

- The percentage is decreasing by 5.6% each year, hence the slope is
.
Then, the <em>equation </em>is:

Step-by-step explanation:
-9 is farther from 0 on the number line.
Answer: i) f(-9)= 66
ii)
.
iii) 
Step-by-step explanation:
The given function :
.
i) For f(-9) , the independent variable is x= -9.
Put x= -9 in given function , we get


Thus , f(-9)= 66
ii) For f(x+1) , the independent variable is x= x+1.
Replace x by x+1 in given function , we get
.

Thus ,
.
iii)For f(-x) , the independent variable is x=-x.
Replace x by -x in given function , we get
.
[∵ (+)(-)=(-)]
Thus , 
Answer: 7200
Step-by-step explanation: the formulae is w times l times h. So you just multiply them all together. 24x15x20= 7200
