Question

Station A
Temperature at Station A after x hours: −8+3x
−8+3·=?

Answer 1

To evaluate the expression \(-8 + 3x\) for a specific value of \(x\), you simply need to substitute the value of \(x\) into the expression.

For instance, if you want to find the temperature at Station A after \(x = 0\), \(x = 1\), or any other specific hour, you would substitute that value in place of \(x\).

1. For \(x = 0\):
\[
-8 + 3(0) = -8 + 0 = -8
\]

2. For \(x = 1\):
\[
-8 + 3(1) = -8 + 3 = -5
\]

3. For \(x = 2\):
\[
-8 + 3(2) = -8 + 6 = -2
\]

4. For \(x = 3\):
\[
-8 + 3(3) = -8 + 9 = 1
\]

Substitute the value of \(x\) you want to evaluate for other calculations. Let me know if you have a specific value in mind!
