To find the pre image you need to back track on the image. To get to the image you used (x-6,y+8). Now you need to use the exact opposite to get back to the pre image. For this you would change the signs to look like (x+6,y-8). Now we just apply this to (-4,1).
(-4+6,1-8)
(2,-7) should be the pre image point.
a. irrational numbers
This is because irrational numbers are number like pi and non perfect square roots, etc
Answer:
158.33 minutes = 2.63 hours
Step-by-step explanation:
Seeing as there are no answer choices, here are all the answers I would think to make. Quick note, associative property of multiplication states that you can change the parenthesis/order of your multiplication in any order and it will stay true, example: (5)(8)(3)=40*3 and 24*5.
Answers: (32)(40)(x), (32)(40x), (32)(8)(5)(x), (32)(8x)(5), (160)(8x), (160x)(8), (160)(8)(x), (32x)(8)(5), (256x)(5), (256)(5x), (256)(5)(x), (1280)(x), (1280x)
A rotation is a transformation that preserves figure shape, figure sizes, angles and lengths.
Therefore,
- option A is false, because rotation preserves sizes;
- option B is false, because rotation doesn't change the figure size;
- option C is true, because rotation preserves figure angles;
- option D is true, because rotation preserves lenghts of segments.
Answer: option C and D.
