Answer:
The rule is y = 8 - x
Step-by-step explanation:
* Lets explain how to solve the problem
- There are 8 oranges in a bowl
- The variable y represents the number of oranges that are left
in the bowl
- The variable x represents the number of oranges that are taken
from the bowl
- To make the rule for these situation we must to write two sides equal
each other
∵ The total number of oranges is 8
∵ The number of oranges that are taken from the bowl is x
∵ The number of oranges that are left in the bowl is y
- We can find the number of oranges that are left by subtracting the
number of oranges that are taken from the total number of oranges
∴ y = 8 - x ⇒ OR ⇒ y = -x + 8
* The rule for the number y of oranges that are left in the bowl as a
function of the number x of oranges that are taken from the bowl
is y = 8 - x
