Question 1203401
c = .5 is the solution.


c is greater than 50
c = .5 is not greater than 50, so this is not part of the solution set.
NOT


1/2 13 is greater than or equal to c
1/2 of 13 = 6.5, so 6.5 is greater than or equal to c.
6.5 is greater than c = .5, so this is part of the solutoon sert.


7.5 is less than or equal to c
7.5 is not less than or equal to c = .5, so this is not part of the soluton set.
NOT


c<-1
c = .5 is not less than -1, so this is not part of the solution set.
NOT


c<2.5
c = .5 is less than 2.5, so this is part of the solution set.


-6 is greater than or equal to c
-6 is not greater than c = .5, so this is not part of the solution set.
NOT


c is less than or equal to 1/2
c = .5 is the same as c = 1/2, so this is part of the solution set.


based on the analysis above, the foolowing are not part of the solution set.


c is greater than 50
7.5 is less than or equal to c
c<-1
-6 is greater than or equal to c
