Both trains travel for 7 time units.
Train A travels 385 distance units, so its speed is

Train B travels 577.5 distance units, so its speed is

Note that the units are not specified, but considering that we're talking about trains, the graph is likely to be showing distance in km (or miles) and time in hours.
Also, the distance traveled by train B is not perfectly aligned with the grid, so I assumed that it was the average between the two ticks of 550 and 605.
Answer:
12(-3x + 2)
Step-by-step explanation:
-1/2 ( 32x - 40) - (20x - 4) = -16x + 20 - 20x + 4 = -36x + 24 = 6(-6x + 4) = 12(-3x + 2)
What do you mean? the decimal is .35 and u can't simplify it anymore
Answer:
f(x)=6
Step-by-step explanation:
3(-4)/2+(-4)
-12/-2
f(x)=6
