OpenStudy (igreen):

You have to multiply -2 to both sides. So what's -2 * 4? @comfylomfy

OpenStudy (anonymous):

8

OpenStudy (igreen):

No, almost..

OpenStudy (igreen):

A negative times a positive is a negative..so what is it?

OpenStudy (anonymous):

-8

OpenStudy (igreen):

Yep, so your answer's gonna be \(-8 \ge x\) or \(x \le -8\)

OpenStudy (amistre64):

does x=0 make a true statement?

OpenStudy (anonymous):

no

OpenStudy (amistre64):

then any x bigger than -8 fails so x has to be smaller than -8

OpenStudy (anonymous):

D?

OpenStudy (amistre64):

4 > 0 is true ....

OpenStudy (anonymous):

yes

OpenStudy (amistre64):

when x=-8 the statements is equal .... when x=0 the statement is still true so we want a solution that says x is bigger or equal to -8

OpenStudy (anonymous):

so D

OpenStudy (amistre64):

on D, is x on the small side or the large side of the '<'

OpenStudy (amistre64):

|dw:1413900786335:dw| the sign tells us which side is smaller and bigger

OpenStudy (anonymous):

oh no c

OpenStudy (amistre64):

if we want it so that x is bigger than -8 ... c is the choice :)

OpenStudy (anonymous):

thanks one more than done one sec

OpenStudy (anonymous):

Solve. –6 ≥ 10 – 8x (Points : 1) x ≥ 2 x ≥ –2 x ≤ 2 x ≤ –2
