1Which step in solving this equation is justified by the ssociative Property of Addition? Consider the sequence of steps to solve the equation: 6v+3(7-5)= 4v - (2v + 1) Given =6y + 3(-5) = 4v - (2y + 1) Step 1 = 6 + 3y - 15 = 4y - (2) + 1) Step 2 => 6v + 3y - 15 = 4y = 2y + 1 Step 3 => 9v - 15 = 4v - 2y = 1 Step 4 => 9v - 15 =- 2y + 4y - 1 Step 5 => 9 = 19 = 2y = 1 Step 6 7 15 = 1 Step 7 = ?v = 14 Step 8 =>= 2

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.

a reflection across line m

step-by-step explanation:

the first transformation is a 90 degree rotation counterclockwise around the point g. this gets to image gh'j'k'. when the image gh'j'k' is reflected over the line  m the result is g'h"j"k". the final transformation is a reflection over the line  m.
