Please help

Answer 2

Do you have a link and I don't know what this is, sorry. :/

Answer 3

no i do not :P

Answer 4

for question 1

when rotating a coordinate 180 degrees The x- and y-coordinates of the pre-image and image are in the same position but with opposite signs.
Therefore, a 180° rotation around the origin can be described in mathematical terms as (x, y) → (-x, -y).

so the answer is A -3,-7.

Answer 5

thanks do yuo know how to do question 2

Answer 6

I'm not 100 percent sure but i would go with D.

If i helped can i have a medal?

Answer 7

Im 100 perecent sure about the first question let me know if i get the second question right

Answer 8

okay i will for sure could you help me with one more by chance ?

Answer 9

what is the solution of the system ? solve using matrices
{ x + 2y=9
{ x+y=1

Answer 10

x=-7,y=8
