What is the solution of the system?
y = −3x
3x + 2y = 6

a.(2, 6)
b.(−1, 3)
c.(−2, 6)
d.(1.5, −4.5)

Which compound inequality could be represented by the graph?

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.
