Answer:
5x+15y=85
Step-by-step explanation:
X and Y are the unknown variables, just add them to 5,(cars), and 15 (minibus)
Answer:
(29,-13)
Step-by-step explanation:
You can tackle this for x and y coordinate separately.
For x, the line starts at -9 and is halfway at 10. The distance between -9 and 10 is 19 so it has another 19 to go, which puts the endpoint at 10+19=29.
Same for y: from 7 to -3 is 10 down, another 10 to go, puts you at -13.
Formula: x,y of midpoint is ((x1+x2)/2, (y1+y2)/2)
C) I think you know the increasing line is the one with 3*x and the other one is -2*x, then the dotted line requires <, instead of <=, the rest I'm sure you can figure out.
Let me know if you need more explanation, but it's to make sure next time you answer someone, instead of asking! :)
