It’s number 12!!!!! I know it already got answered
Answer:
7.1
Step-by-step explanation:
um i think yolo
A reflection across the x-axis has the rule:
(x,y)→(x,-y).
Then:
- A(-1,-1)→A'(-1,1),
- B(0,1)→B'(0,-1),
- C(4,2)→C'(4,-2),
- D(6,0)→D'(6,0),
- E(3,-3)→E'(3,3).
Answer: the vertices of the image are A'(-1,1), B'(0,-1), C'(4,-2), D'(6,0) and E'(3,3).
6(x + y) + (x - y)
<em>use distributive property</em>
= 6x + 6y + x - y
<em>combine like terms</em>
= (6x + x) + (6y - y)
<h3>= 7x + 6y</h3>
