question
determine the value of y, if x is 144.
( y = sqrt{x} - 3 )

Explanation:

Step1: Substitute x with 144

We know that \( x = 144 \), so substitute \( x \) into the equation \( y=\sqrt{x}-3 \). We get \( y = \sqrt{144}-3 \).

Step2: Calculate the square root

The square root of 144 is 12, because \( 12\times12 = 144 \). So now the equation becomes \( y=12 - 3 \).

Step3: Subtract to find y

Subtract 3 from 12. \( 12-3 = 9 \). So \( y = 9 \).

Answer:

\( y = 9 \)
