28. there are 8 oranges in a bowl. write a 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.

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

found it xd it ok yt

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
