Determine the value of y, if x is 49 . y=sqrtx-4 Answer: y=

Substitute x into equation: Substitute the given value of x into the equation. y = sqrt(x) - 4 Since x is given as 49, we substitute 49 in place of x. y = sqrt(49) - 4Calculate square root of 49: Calculate the square root of 49. sqrt(49) is equal to 7 because 7 * 7 = 49. y = 7 - 4Find value of y: Subtract 4 from 7 to find the value of y. y = 7 - 4 y = 3

Q. Determine the value of

y

, if

x

49

\newline

y=\sqrt{x}-4

\newline

Answer:

y=

Substitute $x$ into equation: Substitute the given value of $x$ into the equation. $\newline$ $y = \sqrt{x} - 4$ $\newline$ Since $x$ is given as $49$ , we substitute $49$ in place of $x$ . $\newline$ $y = \sqrt{49} - 4$
Calculate square root of $49$ : Calculate the square root of $49$ . $\sqrt{49}$ is equal to $7$ because $7 \times 7 = 49$ . $y = 7 - 4$
Find value of y: Subtract $4$ from $7$ to find the value of $y$ . $\newline$ $y = 7 - 4$ $\newline$ $y = 3$
