Answer:
The system of equations will have an infinite number of solutions.
Step-by-step explanation:
i) when we arrive at a solution of a linear system with two equations and two
variables and the solution of the equation does not give the value of any
variable but rather is in the form of an identity like the one given, that is
-6 = -6, then we can say that the two equations are exactly the same and
that the system of equations will have an infinite number of solutions.
Winter
Winter comes after fall in the pattern as we see already. Because this is true, winter is next.
Answer:
Step-by-step explanation:
According to question
α−d+α+α+d=−3ba
3α=−3ba
α=−ba
α2−dd+α2+αd+α2−d2=3a
3α2−d2=3ca
3b2a2−h2=3ca
d2=3b2a2−3ca=3b2−3aca2
α(α2−d2)=−da
−ba(b2a2−(3b2−3aca2))=−da
b(b2−3b2+3aca2)=d
−2b3+3ab=a2d
2b3−3abc+a2d=0

The percentage increase in the number of miles travelled by all motor vehicles from 1993 to 2013 is19%.
<h3>
Percentage increase</h3>
Using this formula
Percentage increase=Current data- Previous data/Previous data
Let plug in the formula
Percentage increase=3.058×10^11-2.543×10^11/2.543×10^11
Percentage increase=(3.058-2.543)×10^11/2.543×10^11
Percentage increase=0.459×10^11/2.543×10^11
Percentage increase=0.495/2.545
Percentage increase=0.19×100
Percentage increase=19%
Therefore the percentage increase in the number of miles travelled by all motor vehicles from 1993 to 2013 is19%.

For this data set:
Mean: (3+3+4+4+4+5+5+5+5+30) : 10 = 6.8
Mode : 5
Median : (4+5) : 2 =4.5
In this case, the mean is not the best way to show central tendency.
The median is less affected by outliers and skewed data.
Answer: The best measure for the central tendency is the median: 4.5
