Reflection does not preserve orientation.
Dilation (scaling), rotation and translation (shift) do preserve it.
9 3/4 is heavier than 9 5/8. If you multiply 3/4 by 2/2, you will get 6/8, which is greater than 5/8.
Answer:
-3<y<=3 or B
Step-by-step explanation:
first we find the smallest y value which is -3
then we find the largest y vlaue which is three
so since there is an open circle at negative three we do not include it while at three we do.
so the answer would be -3<x<=3

Answer:
9ab - 9a +1
Step-by-step explanation:
first, we can distribute the negative sign to the second set of parentheses.
-(-4ab + 5) becomes + 4ab - 5
now let's put the values in (5ab-9a-4) side by side with the corresponding values in + 4ab - 5
5ab + 4ab - 9a - 4 - 5
= 9ab - 9a - 9, because 5ab + 4ab = 9ab, -9a is alone, and -4 - 5 = -9.

This implies that, we form a new matrix where the second row of the new matrix is a product of -3 and the second row of the previous matrix.
So, we have:
