Question

determine the value of y, if x is 6.
y = x² - 6

Explanation:

Step1: Substitute x = 6 into the equation

We have the equation \( y = x^2 - 6 \), and we know that \( x = 6 \). So we substitute \( x \) with 6 in the equation, which gives us \( y = 6^2 - 6 \).

Step2: Calculate the value of \( 6^2 \)

First, we calculate \( 6^2 \), which is \( 6\times6 = 36 \). So now the equation becomes \( y = 36 - 6 \).

Step3: Subtract 6 from 36

Then we subtract 6 from 36, \( 36 - 6 = 30 \). So we get \( y = 30 \).

Answer:

\( y = 30 \)
