Question

14. Point A shown on the number line below. Which of the following is the additive inverse of the numberrepresented by point A?A-32-10123A. -3.5B. -2.5C. 2.5D. 3.5

Answer 1

We can see that the point A is in the middle of -2 and -3. To find the additive inverse we need to see how much we have to add to this number to reach the number zero. In this case, since A is equal to -2.5 (the middle of -2 and -3) then the additive inverse is C. 2.5
