Which system of equations represents the matrix shown below?
[1 2 -18
-1 0 3 15
1 -2 4 18
O
x+2y - 7-8
A. -x+y +32 = 15
x-2y + 4z - 18
ti
x + 2y + z = 8
X+V+3 z= 15
x+2y + 4z = 18
O
x+2y - 7-8
c. -x+37 = 15
X -- 2y +47 218
x+2y + z = 8
x +2y + 4z - 18

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.

60%

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
