What is the difference (2 x minus 3) minus (x minus 1)? x minus 4 x minus 2 x + 2 x + 4

Step-by-step explanation:

We want to find the difference:

We expand the parenthesis using the distributive property to get:

Regroup similar terms on the right:

Combine similar terms on the right:

Therefore the difference is x-2

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)
