Determine the value of y, if x is 31 . y=sqrt(x+18) Answer: y=

Substitute x = 31: To find the value of y, we need to substitute the value of x into the equation y = sqrt(x + 18). Let's substitute x = 31 into the equation. y = sqrt(31 + 18)Perform addition inside square root: Now, we need to perform the addition inside the square root. 31 + 18 = 49 So, y = sqrt(49)Find square root of 49: Next, we find the square root of 49. The square root of 49 is 7, because 7 * 7 = 49. Therefore, y = 7

\newline

y=\sqrt{x+18}

\newline

Answer:

y=

Substitute $x = 31$ : To find the value of $y$ , we need to substitute the value of $x$ into the equation $y = \sqrt{x + 18}$ . $\newline$ Let's substitute $x = 31$ into the equation. $\newline$ $y = \sqrt{31 + 18}$
Perform addition inside square root: Now, we need to perform the addition inside the square root. $\newline$ $31 + 18 = 49$ $\newline$ So, $y = \sqrt{49}$
Find square root of $49$ : Next, we find the square root of $49$ . The square root of $49$ is $7$ , because $7 \times 7 = 49$ . Therefore, $y = 7$
