In set builder notation, how do you write the solutions of the inequality? –2 –x ≥ –1 {x|x<1} {x|x>1} {x|x>-1} {x|x<-1}
all of your choices are incorrect, you need an equal sign under the inequality.
the answer is {x|x<-1}
@ZhangYan you can not disregard the equal sign underneath the inequality. The asker probably did not record his/her choices correctly
