6x + 3 = -4y + 11
- 3 - 3
6x = -4y + 8
6x + 4y = -4y + 4y + 8
6x + 4y = 8
6x - 6x + 4y = -6x + 8
4y = -6x + 8
4 4
y = -1¹/₂x + 2

Answer:
The correct answer will be X = 4
Step-by-step explanation:
Using Pythagoras
AB^2 + BC^2 = AC^2
2^2 + (2√3)^2 = AC^2
4 + (4*3) = AC^2
4+12 = AC ^ 2
AC ^2 = 16
AC = √16 = 4
A would be fine as your answer.
