Suppose that on a coordinate plane a hexagon is reflected across the x-axis. Compare the area of the original hexagon to the area of the transformed figure. Justify your answer. A) The areas may or may not be the same because the scale is not given. B) The areas are equal. A reflection is a rigid transformation, which does not change the size of the original hexagon. Therefore, the area is preserved. C) The area of the original hexagon is greater than the transformed figure. A reflection decreases the size of the original polygon. Therefore, the area is not preserved. D) The area of the transformed hexagon is greater than the original figure. A reflection increases the size of the original polygon. Therefore, the area is not preserved.

Answers

Answer 1
Answer:

Reflection along x-axis is just a swapping of left and right sides. It does not change the size or area of the hexagon.

Hence, the correct option is B.

Answer:

It looks like it's going in a distinct pattern

Step-by-step explanation:

3X2=6 5X2=10 9X2=18 17X2=34

But then the pattern stops so I'm not sure if that's right. But, I hope I at least helped in someway!~

Answer: 34,33


Step-by-step explanation: Look at the first five terms. 3,6,5,10 and 9

3x2=6 6-1=5 5x2=10 10-1=9

Multiply by 2 then subtract by 1.

17x2=34 34-1=33

12x-4=2x+6

12x-2x=6+4

10x=10

x=10/10

Therefore:

x=1
The first step is to distribute. So after you do that you should have 
12x-4=2x+6 
Then Isolate your variable by moving the numbers over (remember when they move the change from positive to negative or vise versa) Your equation should now be 10x=10
Once your variable is Isolated simply divide. Then you can plug in your answer to check. Your answer should be x=1

at Mary's party 4/8 of the guest had chocolate ice cream and 3/8 of the guest had strawberry ice cream . what fraction of the ice cream was either chocolate or strawberry

Answers

7/8 because you add 4/8 and 3/8 together which is equal to 7/8.
7/8 I believe, as 4/8 had chocolate ice cream and 3/8 had strawberry and we don't know what the remaining 1/8 had, so just add who had strawberry and who had chocolate together and that will give you the probability.
