X=⁻3 and x=1
because
a+b=2 which means a=3 and b=⁻1 which added up equals 2
a×b=⁻22 which means that 11 which is a×⁻2 which is b=⁻22

Answer:
Whats the question?
Step-by-step explanation:
B a counterclockwise rotation about the origin of 90°
under a counterclockwise rotation about the origin
a point ( x , y ) → (- y, x)
figure Q to figure Q'
( 4,2 ) → (- 2, 4 )
(7, 5 ) → (- 5, 7 )
(3, 7 ) → (- 7 , 3 )
(2, 4 ) → (- 4, 2 )
(5, 4 ) → (- 4, 5 )
the coordinates of the original points of the vertices of Q map to the corresponding points on the image Q'

<em>Question 7:</em> Is the Graph a 1-to-1?
The answer is: No
<em>Reason: </em>If you look at the graph, you see that when the x value is -1 the y value is -2, when x is 0, y is 0. When x is 1, y is 2, when x is 3, y is 4, and so on and so on...
<em>Question 9:</em> What is f(2)?
The answer is: When f (or x) is 2, y is 3... so f(2) = 3
<em>Reason:</em> (Look at reason for Question 7)
