In a quilt pattern, a polygon with vertices
(3,-2), (7, -1), (9,-5), and (5,-6) is
translated repeatedly along the vector
(4, 5). what are the coordinates of the
third polygon in the pattern?

phosphate, calcium ion, chloride ion, neon atom

step-by-step explanation:

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
