A. -9.5B. 9.5C. -2/23D. -2/23Be sure to explain!
the sum of a number and its 'additive inverse' is ALWAYS ZERO !! Does that help ? It should ! archimedes [(- 9.5) + (9.5) 0 ]
9.5 becaue you are looking for the number that will get you to 0
The 'additive inverse' of - 9.5 is 9.5. note: the 'additive inverse' is what needs to be added to the number in order to get the 'additive identity.' the additive identity is zero.
