Am I right?? http://goo.gl/6tRlpm

OpenStudy (alexandervonhumboldt2):

no

OpenStudy (alexandervonhumboldt2):

Add 2 to both sides. we get -x/9<5 multiply both sides by 9. we get −x<5*9 => ?

OpenStudy (briellshaw):

http://goo.gl/sWW8OU srry it was the wrong answer i thought i had D.

OpenStudy (alexandervonhumboldt2):

D is also incorrect

OpenStudy (briellshaw):

B.

OpenStudy (alexandervonhumboldt2):

yeah

OpenStudy (alexandervonhumboldt2):

@pooja195

pooja195 (pooja195):

B is correct

OpenStudy (alexandervonhumboldt2):

why so confusing?

OpenStudy (alexandervonhumboldt2):

it can be done in 3 steps. now is 33

pooja195 (pooja195):

\[\huge~\rm~\bf~\frac{ -1 }{ 9 }x-2<3\] Add 2 \[\huge~\rm~\bf~\frac{ -1 }{ 9 }x-2+2<3+2\] You get this \[\huge~\rm~\bf~\frac{ -1 }{ 9 }x<3+2\] \[\huge~\rm~\bf~\frac{ -1 }{ 9 }x<5\] Multiply by the reciprocal -1/9 ---->9/-1 \[\huge~\rm~\bf~\frac{ 9 }{ -1 }\times \frac{ -1 }{ 9}<\frac{ 9 }{ -1} \times 5\]

pooja195 (pooja195):

From there you get x>-45 Do you understand why it is B? @BriellShaw

OpenStudy (alexandervonhumboldt2):

you sure you did no mistake pooja? like in previous time.

pooja195 (pooja195):

I know i didn't make a mistake. I remembered to flip the sign. When dividing by a negative we flip the sign.

OpenStudy (alexandervonhumboldt2):

previous time you forgot

pooja195 (pooja195):

Yeah we are all humans we were born to make mistakes, that's how we learn from them ^_^

OpenStudy (briellshaw):

Thank You @pooja195 for admitting tht you made a mistake

OpenStudy (briellshaw):

and i uderstand

OpenStudy (alexandervonhumboldt2):

and pooja, looks like in your terms astrophysics gave a direct answer in previous post.

pooja195 (pooja195):

Good ^_^ I apologize for that mistake. <---referring to the previous problem.

OpenStudy (zale101):
