The domain will be x>0 because their cannot be negative people or negative cost of living per person.
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!
sure. or u could google them...
The answer is 7
you want to take your line plot and write each number on it as many times as the dots appear above it. since you have 7 numbers the center would be the 4th one. in order out of these numbers the 7 occurs fourth then giving you your answer.
