Pls help which equation describes the motion of the train?
d=50t
d=25t
d= t- 175
d= t + 25

d = 25t

Step-by-step explanation:

pick tow points on the line, the easier for me is (0,0) and (2,50).  The equation options are given in slope intercept form such as y = mx + b; where m is the slope and be is where the line intercepts the y-axis.  We can see that "b" is zero because the line intercepts the y-axis at 0 (b = 0).

to find the slope you use the two points for the m

m =  =  = 25 is the slope

Therefore the equation should d = 25t

step-by-step explanation:

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
