Q. Determine the value of

y

, if

x

is

144

.

\newline

y=\sqrt{x}-9

\newline

Answer:

y=

Substitute $x$ in equation: Substitute the value of $x$ into the equation. $\newline$ We are given $x = 144$ and the equation $y = \sqrt{x} - 9$ . Let's substitute $x$ with $144$ . $\newline$ $y = \sqrt{144} - 9$
Calculate square root of $144$ : Calculate the square root of $144$ . The square root of $144$ is $12$ because $12 \times 12 = 144$ . $y = 12 - 9$
Subtract $9$ from $12$ : Subtract $9$ from $12$ . Now we subtract $9$ from $12$ to find the value of $y$ . $y = 12 - 9$ $y = 3$
