A pencil costs $x and a notebook cost $4x. I spend $1 000 on pencils and $1 000 on notebooks. a. Write down the number of pencils I get in terms of x?
b. Write down the number of notebooks I get in terms of x?
c. If I get 15 more pencils than notebooks, how much does a pencils costs?

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

the answer is 1030 it's very simple math.
