Answer:
a rotation 90˚ clockwise and then a reflection across the y-axis
Step-by-step explanation:
I'm doing the test right now
First: work out the difference (increase) between the two numbers you are comparing. Then: divide the increase by the original number and multiply the answer by 100. % increase = Increase ÷ Original Number × 100. If your answer is a negative number, then this is a percentage decrease. ( copy and paste from skillsyouneed.com )
-3x-12> 8x + 21
+12 +12
-3x > 8x + 33
-8x -8x
-11x > 33

-11
x < -3
I moved the real numbers to one side and and the variable to the other side to solve for the inequality
I also remembered somewhere that if you divide by a negative number the inequality sign switches.
They are not coplanar because D is not on the same plane.
If you look at the plane made by the front face, it includes points A, B, E, F, J and H. However, C and D are on a different plane made by the back portion of the figure.
