Step-by-step explanation:
If you have any questions about the way I solved it, don't hesitate to ask me in the comments below :)
=
Multiply both sides by 15
6 =
Multiply both sides by c
6c = 30 Divide both sides by 6
c = 5
There's some unknown (but derivable) system of equations being modeled by the two lines in the given graph. (But we don't care what equations make up these lines.)
There's no solution to this particular system because the two lines are parallel.
How do we know they're parallel? Parallel lines have the same slope, and we can easily calculate the slope of these lines.
The line on the left passes through the points (-1, 0) and (0, -2), so it has slope
(-2 - 0)/(0 - (-1)) = -2/1 = -2
The line on the right passes through (0, 2) and (1, 0), so its slope is
(0 - 2)/(1 - 0) = -2/1 = -2
The slopes are equal, so the lines are parallel.
Why does this mean there is no solution? Graphically, a solution to the system is represented by an intersection of the lines. Parallel lines never intersect, so there is no solution.
68% because it’s between them
No, the total cost will be less than $1000.
There will be 7 buses with 44 students each and one bus with 39 students. So in there will be 8 buses in all.
