Answer:
The cost is the same at 10 videos.
Your equations are:
4x
2x + 20
The answer, 10, means that there are 10 videos.
Step-by-step explanation:
First, write out your two equations. It should look like this:
Dreama's Videos: 4x
Membership: 2x + 20
To solve, I keep filling in numbers for x until you get the answer. If you fill in the number 10, for x, you get that it costs $40 for both of them. So, the cost is the same at 10 videos. Your two equations are 4x and 2x + 20. The x represents the number of videos. So, when you get the number 10, it means that there are 10 videos. Hope this helped!
Answer:
Except table 2, all tables have greater unit rate than the graph.
The required arrangements of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < table 7 < Table 6
Step-by-step explanation:
Formula for unit rate :
From the given graph it is clear that the line passes through the points (0,0) and (11,20). So, unit rat of graph is
Similarly, we need to calculate the unit rate for each table.
Except table 2, all tables have greater unit rate than the graph.
The required arrangement of tables is
Table 2 < Table 1 < Table 3 < Table 5 < Table 4 < Table 7 < Table 6
