The function for the cost of materials to make a hat is f(x) = one half x + 1, where x is the number of hats. the function for the selling price of those hats is g(f( where g(x) = x + 2. find the selling price of 10 hats. a. 6 b. 8 c. 10 d. 12

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)
