For a 90 degrees clockwise rotation, the rule is (y, -x)
-6,-5,0,5,6 that is the order from least to greatest
The probabilities of all possible outcomes in a distribution must sum to 1.
The answer is B)
x2+2x−3=0
Factor left side of equation.
(x−1)(x+3)=0
Set factors equal to 0.
x−1=0 or x+3=0
x=1
or
x=−3
This can be rewritten as
(x -6)² = 90 . . . . . the left side is already a perfect square
x -6 = ±√90 . . . . . take the square root
x = 6 ±3√10 . . . . add 6
