(06.06) which of the following demonstrates the commutative property of multiplication? a.5(2a − 3) = 10a − 15 b.10a − 15 = (2a − 3) ⋅ 5 c.5(2a − 3) = (2a − 3) ⋅ 5 d.(5 ⋅ 2a) − 3 = 5(2a − 3)

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.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent
