My guess would be A ! Hope this helps
Step-by-step explanation:
Angle 6 is only equal to angle 2 if the lines are parallel. The horizontal line is being intersected by two lines, if they are parallel then <6 = <2. They are equal because the horizontal line is straight, meaning anything crossing it that are parallel wil creat equal angles
The data is already sorted for us. The median of this set is the middle most value which is 7 (in slot 4; three values to the left and three values to the right).
So the median is originally 7
If we add 5 to each data value we get
3+5 = 8
4+5 = 9
6+5 = 11
7+5 = 12
9+5 = 14
9+5 = 14
11+5 = 16
So the old data set
{3,4,6,7,9,9,11}
shifts to
{8,9,11,12,14,14,16}
after we add 5 to each value
The middle most value of the updated set is 12. It corresponds exactly to the old median of 7.
So we technically didn't even need to add 5 to all of the values to see what the new median would be. We simply need to add 5 to the old median to get the new median
I.e,
(new median) = (old median) + 5
Answer:
-4xy +6x
Step-by-step explanation:
combine like terms
-2xy + 3x - 2xy + 3x
3x + 3x = 6x
-2xy - 2xy = -4xy
-4xy +6x
