Time = distance/velocity = 120/40 = 3 hours
Since there is no picture, I cannot give you a specific answer, but...
To decide if a line best fits a scatterplot you have to look at whether or not the line even remotely makes sense, if the dots are on one side and the line is no where near any of the dots, it is probably not a realistic placement.
If it looks realistic, take a look at if it best fits the dots, is there a line that would touch more or be nearer to more of the dots?
Answer:
54 in one bus
Step-by-step explanation:
96/2=48
48+6=54
(x-8)(x+5)
First thing you do is put the X's into the parentheticals because it is x^2 meaning there are 2 factors with x's. Then, you wonder what factors of -40 could add to get -3. In this case, they are -8 and 5. -8 times 5 is -40 and -8 +5 is -3. Then, you just add -8 and 5 beside the x's in the parentheticals.
