On a coordinate plane, a triangle has points A prime (6, 8), B prime (10, negative 6), and C prime (6, negative 6). What is the pre-image of vertex A' if the image shown on the graph was created by a reflection across the y-axis?

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.

it’s the first one your welcome

x = 12

y = 1

for the points!

the answer is 40.
