At least answer first

1. what linear function can be represented by the set of ordered pairs?

enter your answer in the box.
f(x)=

2. a business spends $3500 to purchase a copy machine. the business also spends $125 per month on maintenance and supplies for the copy machine.

what function equation represents the total cost of the copy machine after x months?

f(x)=125x+3500

f(x)=3500x+125

f(x)=125x−3500

f(x)=3500x−125

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
