Answer:
n = 9
Step-by-step explanation:
Here we have the table:
X Y
4 3
6 5
7 6
10 n
First, we want to find the rule.
in the first pair we have:
x = 4
y = 3
We can see that the y-value is one smaller than the x-value
y = 3 = 4 - 1 = x - 1
For the second pair we have:
x = 6, y = 5
We again can see that the y-value is one smaller than the x-value
y = 5 = 6 - 1 = x - 1
For the third pair we have:
x = 7, y = 6
Again, can see that the y-value is one smaller than the x-value.
y = 6 = 7 - 1 = x - 1
We can conclude that the rule is:
y = x - 1
For the last pair, we have:
x = 10, y = n
Then:
n = 10 - 1 = 9
n = 9
Then the table is:
X Y
4 3
6 5
7 6
10 9
