A student is given a reading list of ten books from which he must select two for an outside requirement. In how many ways can he make his selection?

he can read all f them little by little

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)

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
