Answer:
,
is inconsistent.
Step-by-step explanation:
Two linear equations are inconsistent when each group of coefficients associated with each variable have the same multiple and independent coefficients are different and have the same multiple. Since, the set of variables is
, then the following condition must be observed:
(1)
(2)
(3)
(4)
Now we proceed to check each option:
Option 1:
, ![2\cdot x - y = 7](https://tex.z-dn.net/?f=2%5Ccdot%20x%20-%20y%20%3D%207)
(

,
,
)
,
(This system is not inconsistent)
Option 2:
, ![4\cdot x -y = -2](https://tex.z-dn.net/?f=4%5Ccdot%20x%20-y%20%3D%20-2)
(

)
,
(This system is not inconsistent)
Option 3:
, ![4\cdot x - 2\cdot y = 6](https://tex.z-dn.net/?f=4%5Ccdot%20x%20-%202%5Ccdot%20y%20%3D%206)
(

)
,
(This system is not inconsistent)
Option 4:
, ![6\cdot x -10\cdot y = 14](https://tex.z-dn.net/?f=6%5Ccdot%20x%20-10%5Ccdot%20y%20%3D%2014)

Answer:
2
Step-by-step explanation:
Currently, Peter has run a total distance of
. His goal is 10 km, as stated in the problem, which equates to 10,000 meters. Thus he will need to run
more meters to achieve his goal. Since the track is 400 meters, he needs to run around the track
more times to achieve his goal.
