Rule: The value of k is 15 less than the value of g. Equation: k=g-15 Table:
g
32
37
42
47
52
k
17
22
27
32
37
Practice makes perfect
Let's find the pattern that describes the relation between the dependent variable k and the independent variable g. Note that if we subtract 15 from the value of the variable g we get the value of k. We can include this information in the given table.
g
32
37
42
47
52
Pattern
32- 15
37- 15
42- 15
k
17
22
27
Now we want to write an equation to describe this relationship.
15less than the value ofg=the value ofk
g- 15=k
k=g- 15
We can use this equation to calculate the missing values in the table. Let's first calculate the value of k when g is 47.
