C=chicken
p=pigs
c+p=13~p=13-c (plug in)
2c+4p=40
2c+4(13-c)=40
2c+52-4c=40
-2c=-12
c=6
6+p=13
p=7
6 chickens
7 pigs
I believe it would be 12/18 so that would be 2/3 and 0.6 in decimal form
Please present the relationship in a table arranged vertically:
<span>this relationship. X= 0, 2, 4, 6, Y= 0, 8.4, 16.8, 25.2 becomes:
</span><span> x y
--- -----
0 0
2 8.4
4 16.8
6 25.2
Notice that as x increases by 2 units from 2 to 4, y increases by 8.4 units to 16.8. Thus, the slope of this line is
16.8
m = -------- = 8.4
4-2
Your problem statement sounds incomplete; what were you asked to do here?
You could compare the equations of the 2 functions:
y = 4.2x and
y = 8.4x
The slope of the 2nd function is twice that of the first function. Both graphs go through the origin, (0,0).</span>
