wayra and lily are both hiking along the same trail. wayra is walking at rate of 3.1 kilometers per hour and lily is walking at a rate of 3.6 kilometers per hour . they start their hikes at different time, but at 1:00pm , wayra passes the 3.0 kilometer marker and lily passes the 2.0 kilometer marker a. write a system of equations and solve by using substitutions . round the nearest tenth

lo.lll

step-by-step explanation:

i believe that the answer is

b. y-1=-2(x-4)

hope this !

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)
