Question

Solve and graph. 2|-2x+7|>=18
Would it be x<=-8 and x>=-1???

Answer 1

\[|-2x+7|\ge9\]
\[-2x+7\ge9 or -2x+7\le-9\]

Answer 2

Solve both parts.

Answer 3

2|-2x+7|>=18


|-2x+7|>=18/2


|-2x+7|>=9


-2x+7>=9 or -2x+7<=-9


-2x>=9-7 or -2x<=-9-7


-2x>=2 or -2x<=-16


x<=2/(-2) or x>=-16/(-2) <<<--- this is probably where you made your mistake


x <= -1 or x >= 8
