Answer:-The function f(x) is an arithmetic sequence.


Explanation:-

Let a_1 be the initial value

According to the question

a_2=a_1+4

a_3=a_2+4\\\Rightarrow\ a_3=(a_1+4)+4\\\Rightarrow\ a_3=a_1+4+4\\\Rightarrow\ a_3=a_1+2(4)\\\Rightarrow\ a_3=a_1+2\times4\\\Rightarrow\ a_3=a_1+(3-1)4  and so on

Thus, we can write a formula for the term n of an arithmetic sequence in the form:

a_n=a_1+(n-1)4

where, n=1,2,3,4,....

4= common difference

Therefore, the function f(x) is an arithmetic sequence.

  • An arithmetic sequence is a sequence of numbers in which each term increases or decreases by a constant number.

the local theater is showing a matinee and offering a special deal for the community. A ticket for an adult costs $11 and a tick
Montano1993 [528]
We will call an adult ticket <em>a</em>, and a child ticket <em>c</em>.

Since they sold 60 tickets in total, we can form the equation:
a + c = 60

We can also say that the sum of money from the adult tickets and child tickets combined is 460.
Thus we can say
11a + 6c = 460

Now, we must solve our system.

a + c = 60
11a + 6c = 460

6a + 6c = 360
11a + 6c = 460

-5a = -100
a = 20

Thus, (20) + c = 60
c = 40

a = 20 and c = 40

Three times b less than 100 is equal to the product of 6 and b
Irina-Kira [14]
Not exactly sure which equation you meant:

3(100-b)=6b
300-3b=6b
300=9b
b= about 33

100-3b=6b
100=9b
b=about 11
