thats right thanks

OpenStudy (anonymous):

i forgot lol

OpenStudy (anonymous):

Np. Good luck with your hw

OpenStudy (phi):

the expression on the left is negative (less than zero) if the top is minus and the bottom plus or vice versa you need x+2 ≤ 0 and x-5>0 (top negative, bottom plus) this gives x ≤ -2 and x>5 which is not possible or x+2≥0 and x-5<0 which gives x ≥ -2 and x < 5 which is possible -2 ≤ x < 5

OpenStudy (anonymous):

Phi is correct. My apologies for rushing the answer.

OpenStudy (anonymous):

interval notation would look like [-2,0) U [0,5)

OpenStudy (phi):

one way to do these problems is plot the "zeros" x+2=0 when x= -2 x-5 = 0 when x = 5 then label the region below -2 (both negative ---> positive ---> bigger than 0) -2 to 5 , top +, bottom - --> negative --> < 0 this is the region you want 5 to infinity --> top +, bottom + --> positive --> bigger than 0

OpenStudy (phi):

I would just write [-2, 5)

i understand the problem and the way you explained it thanks for your time @phi and @Plissken
