Determine the value of y, if x is 121. y=sqrtx-3 Answer: y=

Substitute x into equation: Substitute the given value of x into the equation. y = sqrt(x) - 3 Since x is given as 121, we substitute 121 for x. y = sqrt(121) - 3Calculate square root: Calculate the square root of 121. sqrt(121) = 11 This is because 11 * 11 = 121.Subtract 3 from result: Subtract 3 from the square root of 121. y = 11 - 3 y = 8

Q. Determine the value of

y

, if

x

121

\newline

y=\sqrt{x}-3

\newline

Answer:

y=

Substitute $x$ into equation: Substitute the given value of $x$ into the equation. $y = \sqrt{x} - 3$ Since $x$ is given as $121$ , we substitute $121$ for $x$ . $y = \sqrt{121} - 3$
Calculate square root: Calculate the square root of $121$ . $\newline$ $\sqrt{121} = 11$ $\newline$ This is because $11 \times 11 = 121$ .
Subtract $3$ from result: Subtract $3$ from the square root of $121$ . $\newline$ $y = 11 - 3$ $\newline$ $y = 8$
