1. What is the value f(2) given the function f(x)=x+5?*
07
O 8
9
O 10

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)

2nd one in the first row is correct

r = 78539458390583095803458309458039485093485 or just 3
