Which shows the correct substitution of the values a, b, and c from the equation -2 = -x + x2 – 4 into the quadratic formula?
Quadratic formula: x =
-bb2-4ac
2 a
Ox=
-(-1){V - 1)2 - 4(1)(-4)
2(1)
O x=-11/12-46- 1)( - 4)
2(-1)
O x= -13V (1)? - 4( - 1)(-2)
2(-1)
O x=-(-1)+7(-1)2 - 4(1)(-2)
2(1)

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.

the answer is c)8
