Answer:
Function:
Amount earned for 10 hours of work:
Step-by-step explanation:
Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.
Based on the data given in the exercise, you can identify that:
- $140 is a fixed amount.
- For each hour worked on the project, Luigi charges $25. This can be expressed as:
Then, the total amount he charges for a project is the sum of $140 and . This can be represented with the following function:
To calculate the amount of money earned for 10 hours of work, you must substitute into the function and evaluate. Then:
Answer:
<h2>Here's what makes an integer odd:</h2>- It is NOT a multiple of 2.
- When divided by 2, the quotient would be a decimal or have a remainder or fraction.
- It is a multiple of 2.
- When divided by 2, the quotient has a whole number.
<em>The odd numbers from one to 10 are: 1, 3, 5, 7, 9.</em>
<em>The even numbers from one to 10 are: 2, 4, 6, 8, 10. </em>
- With big numbers, if it ends with any of the odd numbers from one to ten, listed above, it would be odd. This goes for the same with even.
- An odd number and even number has a pattern....
[odd, even, odd, even, odd...] [1, 2, 3, 4, 5]
- So, if x was an odd number, adding it by 2, 4, 6, etc. will result in another odd number.
Here's an example:
<em>See how x is an odd number and the sum of the number and two makes another odd number? </em>
The same can go with an even number:
<em>See how x is an even number and the sum of the number and six makes another even number? </em>
I hope my answer helps you understand even and odd numbers.
