Answer:
So, "x increased by 4" can be written as x + 4.
Explanation:
- To translate this phrase into an algebraic expression, we first need to recognize that "increased by" means addition. So, "x increased by 4" can be written as x + 4. This expression means that we're taking some value x, and then adding 4 to it.
- For example: If I asked you what the result is if the number 7 is increased by 4, you would likely say 11. Tracing your work, you realize that you added 7 + 4 = 11. Thus a number increased by 4 is simply: x + 4.
- Anytime you see the word "increased" you know that it means the same as adding.
- Another example would be: v decreased by 10. Notice I changed the letter x to v and changed increased to decrease don't get confused if the letter x is changed to something else. Decrease means subtracting so we know that we are going to take some value b, and then subtract it by 10.
- You can have any letter and it still represent the same thing what I mean is it still represents as x it is just a different variable you will still do the same thing either increase it by a number or decrease it by a number no matter what the variable is.
