Step-by-step explanation:
Let xy = k, where k is the constant of variation.
By using values of x and y in the table,
we see that (2)(48) = (4)(24) = (12)(8) = 96.
Hence k = 96, which is our answer.
Answer: Amount of change : $30
percent increase : 200%
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Wholesale price: $15
</em>
- <em>Retail price: $45
</em>
To obtain the amount of change we have to subtract the wholesale price to the retail price:
Mathematically speaking:
45 -15 = $30
For the percent increase, the amount of change (30) is some percent of the original price (15). So:
30 / 15 =2 (decimal form)
If we multiply it by 100, the percentage is:
200%

Answer:
7²
Step-by-step explanation:
You just need to plot them on a graph and see how many spaces are in between each. So if you plot (1,9) remember it's X, Y axis. Start from zero on the graph. Since it's positive go over 1 to the right and up 9. Then do the same for the rest. Then count how many units are between each point on the graph and find the one that is 5 units apart.
