Answer 1

To interpret the equation for the current temperature in degrees Celsius, where \( x \) is the number of hours after noon, we look at the temperature equation:

\[ T = 2x + 10 \]

The initial value corresponds to the temperature when \( x = 0 \), which is the temperature at noon (0 hours after noon).

Plugging in \( x = 0 \):

\[ T = 2(0) + 10 = 0 + 10 = 10°C \]

Thus, the initial value (the temperature at noon) is 10°C.
