1. What are the coordinates of the circumcenter of a triangle with vertices A(0,1), B(2, 1) , and C(2, 5) ?
2. What are the coordinates of the centroid of a triangle with vertices A(−6, 0) , B(−4, 4) , and C(0, 2) ?
Unfortunately I can not help you
(1/3x+3)=5-x
multiply both sides by three
1x+9=15-3x
add 3x to both sides
4x+9=15
subtract 9 from both sides
4x=3
divide both sides by 4 to isolate x
x=3/4
If you were to simplify your problem it would be 12
Hope i helped, Good Luck!!!!

Answer:
B. 5 hours
Step-by-step explanation:
If the train is going 60mph and we need to find out how long it will be until it is traveling 80mph then we have to do 80-60=20 to figure out how much the speed is changeing. Since every hour the speed increases by 4mph then we have to do how much the train is increasing divided by how much it increases per hour.
20÷4=5
Therefore it will take 5 hours
