Answer:
<u>Line b</u>
Step-by-step explanation:
It cannot be line a or line d because the line will have a constant rate of change. It cannot be line c because line c would be undifined. Therefore, it must be line b.
The function d(t) represents the distance traveled by the train after t hours. d(5) is the total distance traveled by the train after 5 hours, which means 6:00 pm. The d(2) is the total distance traveled by the train after two hours, 3:00 pm. The expression d(5) - d(2) represents the total distance traveled by the train from 3:00 pm to 6:00 pm or for traveling at a constant speed for 3 hours.
Answer: x=−3 and y=13
Step-by-step explanation: y=−4x+1, 11y=x+146
11(-4x+1)=x+14y
y=-4(-3)+1
11(-4x+1)
11(-4x)+11(1)
-11(4x)=11(1)
-44x+11-11=x+146-11
-44x-x=x+135-x
-45x/-45=135/-45
x=-3
-4(-3)+1
12+1
y=13
x=−3 and y=13
Explain your question. no is sure but for me is 7x
