Determine the value of y, if x is 81 . y=sqrtx-11 Answer: y=

Write Equation: First, let's write down the equation given for y in terms of x: y = sqrt(x) - 11 Now, we will substitute x with 81 and calculate the value of y.Substitute and Calculate: Substitute x with 81 in the equation: y = sqrt(81) - 11 Now, calculate the square root of 81.Calculate Square Root: The square root of 81 is 9, since 9 * 9 = 81. So, y = 9 - 11 Now, perform the subtraction to find the value of y.Perform Subtraction: Subtract 11 from 9 to get the value of y: y = 9 - 11 y = -2 This is the final value of y.

Q. Determine the value of

y

, if

x

81

\newline

y=\sqrt{x}-11

\newline

Answer:

y=

Write Equation: First, let's write down the equation given for $y$ in terms of $x$ : $y = \sqrt{x} - 11$ Now, we will substitute $x$ with $81$ and calculate the value of $y$ .
Substitute and Calculate: Substitute $x$ with $81$ in the equation: $\newline$ $y = \sqrt{81} - 11$ $\newline$ Now, calculate the square root of $81$ .
Calculate Square Root: The square root of $81$ is $9$ , since $9 \times 9 = 81$ . $\newline$ So, $y = 9 - 11$ $\newline$ Now, perform the subtraction to find the value of $y$ .
Perform Subtraction: Subtract $11$ from $9$ to get the value of $y$ : $\newline$ $y = 9 - 11$ $\newline$ $y = -2$ $\newline$ This is the final value of $y$ .
