Answer:
Required ordered pair is (0,0) for system of equation
Step-by-step explanation:
The given system of equation is
A). 
B). 
On simplifying the equation A

Take log on both side,
(12x) (log9) = (3y) (log9)
4x=y
To find the solution of the system of the equation :
Replacing value of y=4x in equation B,





We get,
x=0 and x=0.829
Since, 0.829 is not integer number
Only solution of equations is x=0
For the value of y
Replace value x in y=4x=0
Thus, Required ordered pair is (0,0)
Need more information. Can’t answer d=2 the answer would have to be “d”
It would be 12 ones it would be this because you have to add 7+ 5
If it is less than full it means it is anything below 5/5 or 6/6, so they both have less than full water bottles...
If you meant less than half full, Josan has 0.5/5 less than half, so yes, They should stop in this case as well.
You use (y2-y1)/(x2-x1) so if you have two points (ex: (1,2) and (2,4)), plug in those number into the formula
(4-2)/(2-1) = 2/1 = 2 so the slope (or instantaneous rate of change) is 2 for those two points<span />
