I'll teach you how to solve x + 5 ≥ 12 or x*9< 0
--------------------------------------------------------------
x + 5 ≥ 12 or x*9< 0
First lets solve x+5>12:
Subtract 5 from both sides:
x+5-5>12-5
Simplify:
x> 7
Now lets solve x*9< 0:
Divide both sides by 9:
x*9/9 < 0/9
SImplify:
X<0
Combine the intervals:
x [tex]\geq[/tex] 7 or x < 0
Your Answer Is x [tex]\geq[/tex] 7 or x < 0
plz mark me as brainliest :)
