Which graph shows the equation V = 4 + 2t, where V is the total volume of water in a bucket and t is the elapsed time in minutes
Dahasolnce [82]

Answer:

In the picture attached, the graph is shown.

Step-by-step explanation:

No options are provided, so I made the graph.

The equation V = 4 + 2t, is the equation of a line with slope = 2 and y-intercept = 4.

To make a graph, mark some points is helpful. The next points are included in the graph:

t     V  

0    4 + 2(0) = 4

1     4 + 2(1) = 6

2    4 + 2(2) = 8

3    4 + 2(3) = 10

4    4 + 2(4) = 12

5    4 + 2(5) = 14

6    4 + 2(6) = 16

The list price of a refrigerator is $1899. The chain discount is 20/15. What is the final net price?
shusha [124]
1st = 100% - 20% = 80%
2nd= 100%-15% = 85%

Net Price Factor = 0.8 x 0.85 = 0.68

Net Price = $1899 x 0.68

Final Net Price = $1,291.32

Total Discount= $1899 - 1,291.32 = $607.68
