The two lines have different slopes and intersect at one point in the plane. A consistent system is considered to be a dependent system if the equations have the same slope and the same y-intercepts. In other words, the lines coincide so the equations represent the same line.
Answer:
286.5 degrees
Step-by-step explanation:
We want to change radians to degrees
2 pi radians = 360 degrees
5 radians * 360/ 2 pi
900/pi degrees
286.4788976 degrees
286.5 degrees
Answer:
"moderate negative"
Step-by-step explanation:
When two variables are correlated, a tendency, negative or positive, can be distinguished in the dispersion chart.
When the trend is positive it means that one variable increases when the other also increases.
When the trend is negative it means that one variable decreases as the other increases ..
The relationship between both variables can be strong or weak.
If the relationship is strong, the points in the scatter diagram will increasingly resemble a line (if it is a linear relationship).
If the relationship is weak, the points will be more and more scattered without any relation between them.
In this case it is observed that when the years increase the population decreases. Therefore it is a negative relationship. The distribution of the points resemble moderately to a straight line. Therefore, the correct option is "moderate negative"

Answer:
1) 5×5×5
2) False
3) False
Step-by-step explanation:
5³ basically means 5 is multiplied thrice, i.e
5 × 5 × 5
4² = 4×4 = 16
4² is 16, not 8
(-3)² = -3 × -3 = 9
-(3)² = -9
