Determine the value of y, if x is 3 . y=x^(2)+12 Answer:

Substitute x value: Substitute the value of x into the equation. We are given x = 3 and need to find y using the equation y = x^2 + 12. Substitute x with 3: y = 3^2 + 12.Calculate square of x: Calculate the square of x. We need to calculate 3^2, which is 3 * 3. 3^2 = 9.Add 12: Add 12 to the result from Step 2. Now we add 12 to the result of 3^2 to find y. y = 9 + 12.Perform addition: Perform the addition to find the value of y. Adding the two numbers together gives us the value of y. y = 9 + 12 = 21.

Q. Determine the value of

y

, if

x

3

\newline

y=x^{2}+12

\newline

Answer:

Substitute $x$ value: Substitute the value of $x$ into the equation. $\newline$ We are given $x = 3$ and need to find $y$ using the equation $y = x^2 + 12$ . $\newline$ Substitute $x$ with $3$ : $y = 3^2 + 12$ .
Calculate square of $x$ : Calculate the square of $x$ . $\newline$ We need to calculate $3^2$ , which is $3 \times 3$ . $\newline$ $3^2 = 9$ .
Add $12$ : Add $12$ to the result from Step $2$ . $\newline$ Now we add $12$ to the result of $3^2$ to find $y$ . $\newline$ $y = 9 + 12$ .
Perform addition: Perform the addition to find the value of $y$ . $\newline$ Adding the two numbers together gives us the value of $y$ . $\newline$ $y = 9 + 12 = 21$ .
