Questions: Determine the value of y, if x is 31. y = √(x+50)

Transcript text: Determine the value of $y$, if $x$ is 31 . \[ y=\sqrt{x+50} \]

Solution

To find the value of $ y $, substitute $ x = 31 $ into the equation $ y = \sqrt{x + 50} $. Then, compute the square root of the resulting expression.

Step 1: Substitute the Value of $ x $

We start with the equation for $ y $: \[ y = \sqrt{x + 50} \] Substituting $ x = 31 $ into the equation gives: \[ y = \sqrt{31 + 50} \]

Step 2: Simplify the Expression

Now, simplify the expression inside the square root: \[ y = \sqrt{81} \]

Step 3: Calculate the Square Root

Next, we calculate the square root: \[ y = 9.0 \]

Thus, the value of $ y $ is $\boxed{y = 9.0}$.
