How do you graph -y=x+4

Step-by-step explanation:

That is too many, but I have time to do the first question.

If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points. Which grade should be awarded 40 points?  

Step-by-step explanation:

It is given that the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds.

The team’s best time for the race is

56.81+59.22+57.39+60.11=233.53

1 min = 60 sec

Using this conversion we get

233.53/60=3.89

Therefore the team’s best time for the race is 3.89.

If the team’s best time for the race is less than 4 minutes, then the eighth graders earn 40 points. If not, the seventh graders earn 40 points.

Since the team’s best time for the race is less than 4 minutes, therefore the eighth graders earn 40 points.
