-3x - 42 > 3 |+42
-3x > 45 |change the signs
3x < -45 |:3
x < -15 → x ∈ (-∞, -15)
Where is the rest of the question?
Answer:
10.75 , 10 (6/24),13/20,-10(6/25)
For part a,y < x y > -2xPoint B: (3,1) plugin x=3, y=1 y < x 1 < 3which is true, so point B satisfies the first inequality.
Not sure... about part C though sorry...
