The sum of 9 and y is at most 27

9 + y > 28

Step-by-step explanation:

9 + y ≤ 27

Hope this helps!

if you need to know the y value, then y ≤ 18

Hope this helps!

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
