The price of a train ticket consists of an initial fee plus a constant fee per stop.
2 answers:
Answer:
The starting fee is $2.
Step-by-step explanation:
Provided:
Stops Price (dollars)
3 6.50
7 12.50
11 18.50
It is noted that the cost of a train ticket comprises an initial fee along with a fixed fee per stop.
Let's denote the initial cost as 'x'.
Let 'y' represent the constant fee.
This leads us to create the following equation;
According to the table:
For 3 stops, the price equals 6.50
Thus, we can formulate this equation;
Referring back to the table for;
For 7 stops, the cost amounts to 12.50
This similarly creates another equation;
By subtracting the first equation from the second, we obtain;
Inserting the value of y into the first equation results in;
This confirms that the initial fee is $2.

To address this question effectively, it's essential to clarify the characteristics of the given geometric terms.
A quadrilateral is defined as a four-sided figure.
Parallelograms are a subset of quadrilaterals characterized by having two pairs of parallel sides, with congruent opposite sides and angles. Instances of parallelograms include squares, rectangles, and rhombuses.
Trapezoids are also categorized under quadrilaterals but are distinguished by having only one pair of parallel sides.
In our investigation, we seek to determine whether there exists a four-sided shape without parallel sides. The included image presents an example of a quadrilateral that does not qualify as either a parallelogram or a trapezoid. Therefore, in accordance with the definitions of these polygons, the correct choice is B.
