Determine the value of y, if x is 81 . y=sqrtx-8 Answer: y=

Calculate square root: We are given the equation y = sqrt(x) - 8 and the value of x is 81. First, we need to find the square root of x. Calculate the square root of 81. sqrt(81) = 9Substitute into equation: Now that we have the square root of x, we can substitute it into the equation to find y. Substitute 9 for sqrt(x) in the equation y = sqrt(x) - 8. y = 9 - 8Perform subtraction: Perform the subtraction to solve for y. y = 9 - 8 y = 1

\newline

y=\sqrt{x}-8

\newline

Answer:

y=

Calculate square root: We are given the equation $y = \sqrt{x} - 8$ and the value of $x$ is $81$ . First, we need to find the square root of $x$ . $\newline$ Calculate the square root of $81$ . $\newline$ $\sqrt{81} = 9$
Substitute into equation: Now that we have the square root of $x$ , we can substitute it into the equation to find $y$ . Substitute $9$ for $\sqrt{x}$ in the equation $y = \sqrt{x} - 8$ . $y = 9 - 8$
Perform subtraction: Perform the subtraction to solve for $y$ . $y = 9 - 8$ $y = 1$
