Q. Determine the value of

y

, if

x

is

9

.

\newline

y=x^{2}+12

\newline

Answer:

Substitute $x$ in equation: Substitute the value of $x$ into the equation. $\newline$ We are given $x = 9$ and the equation $y = x^2 + 12$ . Let's substitute $9$ for $x$ . $\newline$ $y = 9^2 + 12$
Calculate square of $9$ : Calculate the square of $9$ . $9^2$ is $9$ multiplied by itself. $9^2 = 81$
Add $12$ to result: Add $12$ to the result from Step $2$ . $\newline$ Now we add $12$ to $81$ to find the value of $y$ . $\newline$ $y = 81 + 12$
Perform addition: Perform the addition. $\newline$ Adding $81$ and $12$ gives us the final value of $y$ . $\newline$ $y = 93$
