i can figure this out
i try inverse but im still getting it wrong ive been stuck on this fo awhile
There is no inverse in the equation.
the |...| means absolute value. We perform what is indicated in the |,,| and that is +1. The absolute value of this is 1 (if the answer had been -1 the absolute value still is 1). Then
-2+(+1) = -1. The absolute value of anything is the value of the number ignoring the sign.
