Answer:

Step-by-step explanation:
Factor the expression by first finding a GCF. Each term has the y variable and this can be pulled out as the GCF.

To further factor the expression break the polynomial into two binomials.
To factor into two binomials, find factors that multiply to -5 and add to -4.
-5 and 1 are factors and these make the binomials
.
The final factorization is 
Answer:
180 degree clockwise rotation about center and a dilation of 0.5.
Answer:
2/3
Step-by-step explanation:
It moves to the right 3 and up 2.
CB is equal to 10m you can tell this bye the side DC being 20 m and the angle of DC is half of CB so that means that CB has to be 10 m
