2(x-3)+5>39

Please explain how to get it!

x > 20

Step-by-step explanation:

first, i removed the parentheses.

2x - 6 + 5 > 39

then i calculated it.

2x - 1 > 39

then, i moved the constant to the right.

2x > 39 + 1

then, i added the two.

2x > 40

finally, i divided both sides.

solution: x > 20

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.
