The answer I got to this was 2.3 but I don't know if that's correct.
Your answer is 27.0 because to get your answer, you need to multiply 5.4x5
Answer: 9 on the x axis and 18 on the y axis
3k²+11k+6, or (k+3)(3k+2), which is the 3rd one. :)
For the first one Y = -6
3x + 2Y = -16
-2y -2y
3x = -18y
— —
3x 3x
Then divide -18y divided by 3X
To get Y= -6
Hope that helped!
