Answer:
-2x^2-3x-9+-3x^2-4+6
16x - 3x - 9 + 9x - 4 + 6
13x - 9 + 9x + 2
13x + 9x -9 + 2
21x -7
Step-by-step explanation:
-2x^2-3x-9+-3x^2-4+6
16x - 3x - 9 + 9x - 4 + 6
13x - 9 + 9x + 2
13x + 9x -9 + 2
21x -7
2x - 6 <span>≥ 6(x - 2) + 8
2x - 6 </span><span>≥ 6x -12 +8
2x -6 </span><span>≥ 6x -4
-6 -6
2x </span><span>≥ 6x -10
-6x -6x
-4x </span><span>≥ -10
x < 2/5</span>
