tell whether each statement is sometimes, always, or never.
1) the value of the expression -2 + n is less than value of n. answer always.
2) when b is positive, the expression -b + (-b) is equal to 0. answer always.
3) when x is negative, the value of the expression x+1 is negative. answer always.
are these correct?
Try plugging in these numbers for each of the problems and seeing if the statements are always true.
2)If b is 2, then you have -2 + -2 = -4...
3)Try to plug in x=-1
