Answer 1

To fill in the output based on the input and the given operation ("double the input, then add 5"), we can follow the steps for each input value.

The formula based on the input \( x \) is: \[ \text{output} = 2 \times x + 5 \]

Now we will calculate the output for each given input:

1. Input: 9 \[ \text{output} = 2 \times 9 + 5 = 18 + 5 = 23 \]

2. Input: 12 \[ \text{output} = 2 \times 12 + 5 = 24 + 5 = 29 \]

3. Input: 7 \[ \text{output} = 2 \times 7 + 5 = 14 + 5 = 19 \]

4. Input: 5 \[ \text{output} = 2 \times 5 + 5 = 10 + 5 = 15 \]

Putting it all together, the completed table will look like this:

Input | Output ---|--- 9 | 23 12 | 29 7 | 19 5 | 15
