For this case we have the following expression:
For power properties we have:
In the division, when we have the same base, the exponents are subtracted.
We then have to rewrite the expression:
Answer:
Completing the expression we have:
Answer:
The equation representing the proportional relationship between j and m is m = 3j/4 .
Step-by-step explanation:
Writing an Equation to Represent a Proportional Relationship
What is proportional relationship?
A proportional relationship between two quantities is when the two quantities vary directly with one and other. Meaning if one item is doubled, the other item is also doubled.
Going back to the given problem above, we have the table showing the proportional relationship between j and m.
j | 4 | 12 | 20 |
m | 3 | 9 | 15 |
Solution:
Step #1
The proportional relationship can be written as:
m/j = ¾ = 9⁄12 = 15⁄20 = ¾
Step #2
So, the equation representing this proportional relationship is:
m = ¾ × j/1 = 3j/4
Final Answer:
The equation representing the proportional relationship between j and m is m = 3j/4 .
