Question

determine the value of y, if x is 19.

( y = sqrt{x + 17} )

answer

Explanation:

Step1: Substitute x = 19 into the equation

We have the equation \( y = \sqrt{x + 17} \). Substitute \( x = 19 \) into it, so we get \( y=\sqrt{19 + 17} \).

Step2: Calculate the value inside the square root

First, calculate the sum inside the square root: \( 19+17 = 36 \). So now the equation becomes \( y=\sqrt{36} \).

Step3: Find the square root of 36

The square root of 36 is 6, because \( 6\times6 = 36 \). So \( y = 6 \).

Answer:

6
