Answer:
(-1,1), (1,3), (2,2)
Step-by-step explanation:
To dilate an object, we need to multiply the x and y values by the given scale factor.
In this case the scale factor is 1/3 --> 1/3(x, y)
Before-> After dilation
1/3(-3,3) = (-1,1)
1/3(3,9) = (1,3)
1/3(6,6) = (2,2)

Step-by-step explanation:
|4x + 8| > 2
Therefore 4x + 8 > 2 or 4x + 8 < -2.
When 4x + 8 > 2, 4x > -6, x > -1.5.
When 4x + 8 < -2, 4x < -10, x < -2.5.
Hence, x < -2.5 or x > -1.5.
