Find the midpoint of the segment with endpoints of (-12, -9) and (2, 10) and enter its coordinates as an ordered pair. if necessary, express coordinates as fractions, using the slash mark ( / ) for the fraction bar.

We're looking at the difference between the coordinates here i.e. 

Therefore, 2-(-12)=14 and 10-(-9)=19
Halving both of these gives 7 and 9.5, since the difference gets you all the way along the line segment, so halving it will get you to the midpoint.

Adding 7 to -12 gives -5, adding 9.5 to -9 gives 0.5 (1/2)

Putting these together, this gives the coordinates (-5,1/2)

Answer for 2: his profit would be $2.88 explanation: you have to first multiply 72 and 0.12 together to get $8.64 once you do that you know how much money the shopkeeper made from selling the candy bars individually. so you have to do 8.64-5.76=2.88 hope that ; )answer for 3: yeah i’m sorry i have no idea what number 3 is. i’m sorry i couldn’t with that.
