B=-3
because you divide 27 by -9 to get y by its self
Answer:
A. The reflection preserves the side lengths and angles of triangle . The dilation preserves angles but not side lengths.
Step-by-step explanation:
Reflection is a rigid transformation. It preserves both angles and side lengths. Dilation preserves angles, but changes all lengths by the same scale factor.
<h3>Application</h3>
The described triangle was subject to reflection, which preserves angles and lengths. It was also subject to dilation, which preserves angles, but not lengths.
The appropriate description is that of choice A.
Answer:
1. alternate exterior angles
2. co-interior angles
3. corresponding angles
4. alternate interior angles
5. corresponding angles
6. co-interior angles
Answer:
5/6
Step-by-step explanation:
5/10 + 2/6
First find the common denominator by multiplying 5/10 by 3/3
5/10*3/3=15/30
Then to get to that same denominator multiply 2/6 by 5/5
2/6*5/5=10/30
Answer:
15/30+10/30= 25/30
Then divide 25/30 by 5/5
25/30 / 5/5 = 5/6
