The unit rate of 521 miles in 14 hours is 37.214 miles per hour.
Slope = Y2-Y1/X2-X1 = 7-(-3)/3-(-2)= 10/5 = 2
The pair of linear equations has a unique solution. Then the pair of equations is consistent and independent.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Given
are the linear equations.
We know the condition,

The pair of equations satisfies the condition.
The pair of linear equations has a unique solution.
If a system has at least one solution, the system is consistent.
If the consistent system has exactly one solution then the system is independent.
Thus, the pair of equations is consistent and independent.

F=4,which is something of an answer
That is hard. I'm guessing that they still are the same shapes but they all have different lengths in certain areas that make them seem like they are the same shapes but are being seen at different angles but I can't be sure. That's why they are in the same groups although having different angles. Does it have answer choices? I will help you if it does...
