lukranit [14]
Okay to solve this problem you would simply do this solution. It took me a minute, haven't had to do integers in a while. :D

From 10,000 to 99,999 the numbers divisible by 5 ends in 0 or 5.
The first (most significant) digit can be any of nine from 1 to 9.
The 2nd digit can be any of 10.
The 3rd digit can be any of 10.
The 4th digit can be any of 10.
The 5th digit can be either of 2.

<span>That's 9(10)(10)(10)2=18,000

I hope this helps.

Range: (-1, 5)

General Formulas and Concepts:

<u>Algebra I</u>

  • Domain is the set of x-values that can be inputted into function f(x)
  • Range is the set of y-values that are outputted by function f(x)

Step-by-step explanation:

According to the graph, the line's x-values span from -5 to 1. Since both are open dot, they are exclusive from the domain:

Interval Notation: (-5, 1)

Inequality Notation: -5 < x < 1

According to the graph, the line's y-values span from -1 to 5. Since both are open dot, they are exclusive from the range:

Interval Notation: (-1, 5)

Inequality Notation: -1 < y < 5
