Are the graphs of 2x+7y=6 and 7y = 2x +6 parallel? explain.
Answer from: carterlewis02
With questions like this (to see if theyre parallel), all you have to do is see if lines have a congruent slope. if yes (ex: 2 and 2), then they are parallel. if the slopes are opposites (ex: 4 and -1/4), then they are perpendicular. If they have no such relation (ex: -3 and 1/7), then they are neither.
with this problem, find the slope by separating the same variable in each equations, like this:
2x + 7y = 6
-2x -2x
7y = -2x + 6
(the second equation is already separated) so now we have
7y = -2x + 6 and 7y = 2x + 6
since -2 does NOT equal 2, these two graphs/lines are NOT parallel.
Hope this helped!

54 kilometers per hour
step-by-step explanation:
according to rules:
1 km = 1000 meter
which means that 1 meter = 1/1000 km
1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]
which means that 1 second = 1/3600 hour
therefore, 1 kilometer/hour =
thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.
15 meter/second= which is the required answer.
