Sure, let's solve the problem step-by-step.
1. Representing 212 feet below sea level:
When something is "below sea level," it is considered to have a negative value because it is below the reference point (which is sea level). Therefore, 212 feet below sea level would be represented as:
[tex]\[
-212
\][/tex]
2. Representing 900 deposited in a bank:
When money is deposited in a bank, it is considered an increase or a positive transaction. Therefore, depositing 900 dollars in a bank would be represented as:
[tex]\[
+900 \text{ or simply } 900
\][/tex]
So the numbers represented with appropriate signs are:
- 212 feet below sea level: [tex]\(-212\)[/tex]
- 900 deposited in a bank: [tex]\(900\)[/tex]
These are the integer representations of the given situations.
