Not a robot! I don't think.
Y in the beginning goes up to 3.
Y in the end goes down to -2 before shooting back up in an infinite sense.
Increasing: The beginning and the end the line on the graph. (Also the jump in the middle, the round part.)
Decreasing: The middle of the graph. (The jump, downward slope.)
Constant, Y at the near end going in a straight line from 9-12 at a -2.
End behavior: Decide for yourself. Is the line going up without fault at the end an appearing continuous or a discontinuous line?
Answer:
The system of linear equations are
and 
Step-by-step explanation:
Given : The number of students who chose lunch was 5 more than the number of students who chose breakfast. Let x represent the number of students who chose breakfast and y represent the number of students who chose lunch.
(50 students picked, 25 picked dinner the rest picked lunch and breakfast)
To find : Write a system of linear equations that represents the numbers of students who chose breakfast and lunch ?
Solution :
The number of students who chose breakfast be 'x'
The number of students who chose lunch be 'y'.
The number of students who chose lunch was 5 more than the number of students who chose breakfast.
i.e. 
Now, Total student were 50 and 25 picked dinner the rest picked lunch and breakfast i.e. 25.
So, 
Therefore, the system of linear equations are
and 
If a light bulb consumes 600 per day, then you need to divide 2250 by 600. So it would be around 3.75 days
The correct answer is 42x^4-24x^3+12x^2
If you work out the difference between 2 and 7 you will get 4 so you add 4 each time.
3=12
4=16
5=20
