Determine the value of y, if x is 4. y=sqrtx-5 Answer: y=

Substitute x into equation: Substitute the value of x into the equation. y = sqrt(x) - 5 Since x is given as 4, we substitute 4 into the equation. y = sqrt(4) - 5Calculate square root of 4: Calculate the square root of 4. sqrt(4) is 2 because 2 * 2 = 4. y = 2 - 5Subtract 5 from 2: Subtract 5 from 2. y = 2 - 5 y = -3

Q. Determine the value of

y

, if

x

4

\newline

y=\sqrt{x}-5

\newline

Answer:

y=

Substitute $x$ into equation: Substitute the value of $x$ into the equation. $\newline$ $y = \sqrt{x} - 5$ $\newline$ Since $x$ is given as $4$ , we substitute $4$ into the equation. $\newline$ $y = \sqrt{4} - 5$
Calculate square root of $4$ : Calculate the square root of $4$ . $\sqrt{4}$ is $2$ because $2 \times 2 = 4$ . $y = 2 - 5$
Subtract $5$ from $2$ : Subtract $5$ from $2$ . $\newline$ $y = 2 - 5$ $\newline$ $y = -3$
