Create a system of 2 equations

Let x be daily fee and y the mileage charge, then

4x + 370y = 244.50...........(1)

3x + 190y = 161.50..............(2)

If we multiply (1) by 3 and (2) by -4 and add the 2 equations we eliminate x:-

12x + 1110y = 733.50

-12x - 760y = -646 Adding :-

350y = 87.5 so y = 0.25

Plugging y = 0.25 into eqation (1) we get 4x = 244.50 - 0.25 * 370

giving x = 38

Answer is daily fee = $38 and mileage charge = $0.25 per mile.

the terms in sequence A increases by 3. The terms in sequence B increase by 8. In which sequence do the terms form a steeper lin
il63 [147K]

Solution: The sequence B shows the steeper line.

Exanation:

The line having greater slope is always steeper than the other lines.

Since it is given that the sequence A increases by 3 and the sequence B increases by 8. It means for each additional value the sequences increased by 3 and 5 units respectively.

The slope of line is rate of change of one variable with respect to another variable.

The sequence A increased by 3, therefore the slope of line of sequence A is 3.

The sequence B increased by 8, therefore the slope of line of sequence B is 8.

Since the slope of sequence B is greater than the slope of sequence A, therefore the line of sequence B is steeper than the line of sequence A.

The sequence A can be defined as 3,6,9,12,.... and the sequence B can be defined as 8,16,24,....

So the coordinates points of sequence A are (0,0)(1,3),(2,6) and the coordinates points of sequence B are (0,0),(1,8),(2,16).

From the given figure it is notes that the blue line is steeper than red line.

Therefore, the sequence B shows the steeper line.
