Answer:
each van carries 7 students
each bus carries 60 students
Step-by-step explanation:
let v = # students in a van
let b = # students in a bus
system of equations:
13v + 2b = 211
4v + 4b = 268
I multiplied the 1st equation by -2 to eliminate the 'b' terms
-26v - 4b = -422
+ <u>4v + 4b = 268</u>
-22v = -154
v = 7
substitute '7' for 'v':
4(7) + 4b = 268
28 + 4b = 268
4b = 240
b = 60

Answer:
x=5
Step-by-step explanation:15x - 10x -2 = 23
5x= 23 = 2
5x = 5
x=5
Answer:
No
Step-by-step explanation:
Every x value in the domain should only have 1 y value. In the graph, for x=5 (the input) there are 2 y values (6 and -6) so this is not a function.
Note that points that lie on an axis do not lie in any quadrant. If a point lies on the x-axis then its y-coordinate is 0. Similarly, a point on the y-axis has its x-coordinate 0. The origin has coordinates
