Determine the value of y, if x is 1. y=sqrtx-9 Answer: y=

Substitute x into equation: Substitute the value of x into the equation. Since x is given as 1, we substitute 1 for x in the equation y = sqrt(x) - 9. y = sqrt(1) - 9Calculate square root of 1: Calculate the square root of 1. The square root of 1 is 1, because 1 * 1 = 1. y = 1 - 9Subtract 9 from 1: Subtract 9 from 1. Perform the subtraction to find the value of y. y = 1 - 9 y = -8

, if

x

\newline

y=\sqrt{x}-9

\newline

Answer:

y=

Substitute $x$ into equation: Substitute the value of $x$ into the equation. $\newline$ Since $x$ is given as $1$ , we substitute $1$ for $x$ in the equation $y = \sqrt{x} - 9$ . $\newline$ $y = \sqrt{1} - 9$
Calculate square root of $1$ : Calculate the square root of $1$ . The square root of $1$ is $1$ , because $1 \times 1 = 1$ . $y = 1 - 9$
Subtract $9$ from $1$ : Subtract $9$ from $1$ . $\newline$ Perform the subtraction to find the value of $y$ . $\newline$ $y = 1 - 9$ $\newline$ $y = -8$
