to form a perfect square.
Comparing the given expression to

we have
a=1 , b=-3 , and c=0.
We need to add

We substitute the values to get,

We change this to mix numbers to get,

The last choice is correct.
Answer:
G'(1, 3)
Step-by-step explanation:
Counterclockwise rotation 90°: (x, y) ⇒ (-y, x)
So the point G is transformed to ...
... G(3, -1) ⇒ G'(1, 3)
I think it is A. not sure though
<span>Assuming that Josh throws the discus 36 times, the expected value of y will be the length each discus reaches for each throw all added together. Specifically, it will be discus throw one, plus discus throw two -- all the way to discus throw thirty-six. Adding all of those throws together will provide the expected value of Y.</span>
A(3,4) B(-3,2) C(-2,-4) D(6,-3)
