To solve the compound inequality
OpenStudy (haleyelizabeth2017):
\[-2 \le d+\frac{ 1 }{ 2 } < 4 \frac{ 1 }{ 2 }\] is this what it looks like?
OpenStudy (bieber896):
haha yes

you got it correct but it is actually written as \(-2\frac{ 1 }{ 2 } \le d < 4\)
OpenStudy (anonymous):
Yea, I think that is right because you have to remove the 1/2 from the middle. I barely remember this, but it looks right. Good job Haley
OpenStudy (haleyelizabeth2017):

-2 <= d + 1/2 <= 4 1/2
-2 <= d + 1/2 <= 9/2 -- subtract 1/2
-2 - 1/2 <= d <= 9/2 - 1/2
-4/2 - 1/2 <= d <= 8/2
-5/2 <= d <= 4 or - 2.5 <= d <= 4
yep..you got it
OpenStudy (anonymous):
oops...there is not supposed to be an equal sign...it should be :
-2.5 <= d < 4
OpenStudy (bieber896):
@kelliegirl33 but what if there are 2 variables?
OpenStudy (anonymous):
give me an example
OpenStudy (anonymous):
oh crap..I lost track of time. Sorry....I will be back on later
