Answer:
Midpoint: (2.4, -1)
Step-by-step explanation:
Midpoint Formula: ![(\frac{x1+x2}{2} , \frac{y1+y2}{2} )](https://tex.z-dn.net/?f=%28%5Cfrac%7Bx1%2Bx2%7D%7B2%7D%20%2C%20%5Cfrac%7By1%2By2%7D%7B2%7D%20%29)
With that in mind,
(3.2 + 1.6)/2 = 2.4
(2.5 - 4.5)/2 = -1
Additive inverse is the negative of the number, i.e. what you add to the number to get zero.
So the additive inverse of number b is - b
Additive inverse of 4 is - 4.
Then, you can verify the subtraction is the same that add the additive inverse.
For example subtracting 4 from 10 (10 - 4) is the same that adding -4:
10 - 4 = 10 + (-4).
Then given any expression if you have to subtract other expressión you just add the addive inverse of the second expression.
For example: given A(x) = x^2 + 3x + 5 and B(x) = 2x + 4
Find A(x) - B(x) = A(x) + [-B(x)]
=> x^2 + 3x + 5 + (-2x -4) = x^2 + 3x - 2x + 5 - 4 = x^2 + x + 1
