Answer 10

You have been helping me SO much, thank you so so so much!

Do i count the blocks ?

Answer 13

there is no numbers on the y and x axis's so it was confusing to me

Answer 14

Answer 15

Oh so the answer is D? A to D is 4 blocks down and B to E is 7 blocks down

Answer 16

u turn A and move it down?

Answer 17

Answer 22

on your keyboard should be a "prt scrn" key

hit that key, then open up MS paint and go to edit --> paste

edit/crop if needed, save it, then send it

Answer 23

the "prt scrn" key is normally in the top right portion of the keyboard
around the "insert", "delete", etc

Answer 24

what is point P? the coordinates of it

Answer 25

(-2,1)?

Answer 26

you have it flipped

it should be (1,-2)

Answer 27

x comes first

Answer 28

oh ok

Answer 29

now multiply each coordinate by 2.5 to get your answer

Answer 30

2 1/2 and -5

Answer 31

so 2.5 and -5

Answer 32

yep (2.5, -5)

Answer 33

Thank You for helping me learn how to do that! My next question was like that question and I knew exactly how to do it(:

Answer 34

I'm glad it's making sense

Answer 35

(:

Answer 36

I think it would be V?

Answer 37

or R?

Answer 38

This problem is just awful. It makes no mention at all if point C is on line RS (extend out segment RS). The other info seems not that useful either

Answer 39

it looks like C is on line RS, but I can't be sure

anyways, IF that is true, then aiming at point R will reflect onto point D

Answer 40

So im thinking its point R

Answer 41

Thanku

Answer 42

yeah I'm thinking that too

Answer 43
