The students in Ms. Chang's class decide to order water bottles that advertise the walkathon. Hyun obtains two different quotes for the costs of the bottles. a. For each company, write an equation Hyun could use to calculate the cost for any number of bottles b. On the same set of axes, graph both equations from part (a). Which variable is the independent variable? Which is the dependent variable? C. From which company do you think the class should buy water bottles? What factors influenced your decision? d. For what number of water bottles is the cost the same for both companies? Explain.

Answers

The students' order of water bottle is an illustration of linear equation

  • The equations are y = 54x and y = 525 + 53x
  • The class should buy water bottles from Fill it Up Inc
  • 525 water bottles costs the same for both companies

The equation for the cost of bottle

For Fill it Up Inc, we have:

Cost = $54 per bottle

For Bottles by Bob, Co, we have:

Set-up fee = $525

Cost = $53 per bottle

So, the equations are:

  • Fill it Up Inc: y = 54x
  • Bottles by Bob: y = 525 + 53x

The number of bottle (x) represents the independent variable, while the total cost (y) represents the dependent variable

The graph

See attachment for graphs

The class decision

The class should buy water bottles from Fill it Up Inc, because Fill it Up Inc do not charge set-up fee, and the company's rate per bottle is just a little above Bottles by Bob

The number of bottle at equal cost

In (a), we have:

y = 54x and y = 525 + 53x

Substitute 54x for y in the second equation

54x = 525 + 53x

Subtract 53x from both sides

x = 525

Hence, water 525 water bottles costs the same for both companies

Evaluate the following y^2-5y+2

Answers

If y = 3, then you substitute 3 into wherever it says y.

So the original: 
y² - 5y + 2

becomes:
3² - 5×3 + 2.

which is:
9 - 15 + 2.

9 - 15 = -6
-6 + 2 = -4.

-4 is the answer.

Answers

Line A has a slope of 4/3
Line B has a slope of 4/2
The answer is Line B

Final answer:

The steeper line is determined by comparing the slopes of the two lines. The line with the larger slope value is the steeper line. However, the actual slopes of Line A and Line B in the question are not provided.

Explanation:

From the question, it seems like there are two given lines - Line A and Line B but no specific data is provided about their slopes. Therefore, with the information given, we can't determine which line has the steeper slope. Essentially, the steeper line would be the one with the higher slope value when represented in the form: y = mx + c, where 'm' is the slope. For instance, if Line A had an equation of y = 2x +1 and Line B an equation of y = 4x + 1, Line B's slope is steeper because it has a larger 'm' value compared to Line A.

Is the points (0,6) (3,3) (6,-1) on the same line

Answers

To determine if the points (0,6), (3,3), and (6,-1) are on the same line, you can calculate the slope between each pair of points. If the slopes are the same, then the points are collinear (on the same line).

Let's calculate the slopes between these points:

Slope between (0,6) and (3,3):

Slope = (y2 - y1) / (x2 - x1)

Slope = (3 - 6) / (3 - 0)

Slope = (-3) / (3)

Slope = -1

Slope between (3,3) and (6,-1):

Slope = (y2 - y1) / (x2 - x1)

Slope = (-1 - 3) / (6 - 3)

Slope = (-4) / (3)

Slope = -4/3

The slopes between the points are not the same. The first slope is -1, and the second slope is -4/3. Therefore, these points are not collinear and do not lie on the same line.
