Question

determine the value of y, if x is 49.

$y = \sqrt{x - 13}$

Explanation:

Step1: Substitute x = 49 into the equation

We have the equation \( y = \sqrt{x - 13} \). Substitute \( x = 49 \) into it, we get \( y = \sqrt{49 - 13} \).

Step2: Calculate the value inside the square root

First, calculate \( 49 - 13 = 36 \). So the equation becomes \( y = \sqrt{36} \).

Step3: Find the square root of 36

The square root of 36 is 6, because \( 6^2 = 36 \). So \( y = 6 \).

Answer:

6
