What are the solutions of the inequality? Check the solutions. 4x + 6 < –6 A. x < –3 B. x > –3 C. x > –6 D. x < + 6

OpenStudy (kropot72):

4x + 6 < -6 The first step in finding the solution is to subtract 6 from both sides. Can you do that?

OpenStudy (anonymous):

I'm afraid not. I am not too good with math.

mathslover (mathslover):

\[\large{4x+6<-6}\] \[\large{4x+6-6<-6-6}\] what is 6-6 ? @zigzagoon2000

question to ask is: for what values of x does the inequality hold true?

OpenStudy (anonymous):

I have absolutely no idea man

mathslover (mathslover):

good what is -6-6 ? @zigzagoon2000

mathslover (mathslover):

\[\large{-6-6 = ? }\]

OpenStudy (anonymous):

-12

OpenStudy (anonymous):

answer is B

mathslover (mathslover):

hud now we have : \[\large{4x<-12}\] \[\large{x<-3}\]

OpenStudy (anonymous):
