Answer 1

To solve for \( y \) after 12 minutes using the equation \( y = 10x + 20 \):

1. Substitute \( x = 12 \) into the equation:

\[ y = 10(12) + 20 \]

2. Calculate \( 10 \times 12 \):

\[ 10 \times 12 = 120 \]

3. Now, add 20:

\[ y = 120 + 20 = 140 \]

So, \( y = 140 \).

The temperature of the water after 12 minutes is \( 140 \) degrees Celsius.
