The variable Z is directly proportional to X. When X is 6, Z has the value 18.

What is the value of Z when X = 10

Yo sup??

let the relation be

z=Kx

when z=18 , x=6

18=k6

k=3

z=3x

when x=10

z=3*10

=30

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)

10 - 8 = -2

  8 - 6 = -2

etc, so -2 is the common difference
