so it will end up at 6y-6
you need to combine everything that does not have an exponent (example. a, x, y) and you combine the ones that have exponents together. and therefore you get 6y-6 (remember positive and negative signs)
Well it would be 24/24 chances of picking blur because all of them a blue
Answer:
(4,-1), (3,-1),(2,-1) or (1,-1)
if you draw a horizontal line through the point (5,-1) you will notice it crosses through every point ending with -1
3.2 and 3.1 or 3.3 and 3.0
Observe the given figure.
Here, angle T and R are the inscribed angles.
And sum of inscribed angles is half of measure of intercepted arcs.
Since, the measure of intercepted arcs is 360 degrees.
Therefore, 

Hence, the sum of the two angles is 180 degrees.
Therefore, these are the supplementary angles.
Therefore, angle T and angle R are supplementary angles.
Hence, proved.
