ted wrote the following ruleand exspresion to represent the relationship between a and b in the input/output table
input a 9 15 21 24 36
output b 7 9 11 12 16
what did ted forget to do when he wrote the rule and exspresion
Based on the given input/output table, it appears that Ted is trying to establish a relationship between the variables a and b. The given values suggest that there might be a pattern or rule that relates the two variables. Let's analyze the relationship between a and b from the given table:
When a = 9, b = 7
When a = 15, b = 9
When a = 21, b = 11
When a = 24, b = 12
When a = 36, b = 16
From the given inputs and outputs, it seems that the rule for the relationship between a and b is that b is equal to a divided by 3, plus 4. Therefore, the expression that represents this relationship is:
b = (a / 3) + 4
Now let's review what Ted might have forgotten when writing the rule and expression:
1. Ted forgot to mention any constraints on the variables a and b. Are there any limitations or specific ranges for these variables? Providing additional information about the possible values of a and b can make the rule and expression more accurate.
2. Ted did not explain or justify why this particular rule or expression is applicable. Adding some reasoning or explanation can help to understand the relationship more effectively.
3. It is also possible that Ted might have overlooked any exceptions or outliers in the given data. Double-checking the table for any inconsistencies or missing values is important for accuracy.
Remember, when writing rules or expressions to represent relationships between variables, it is essential to provide clear explanations, consider any limitations or constraints, and ensure accuracy by reviewing the data thoroughly.
