Question

determine the value of y, if x is 64.

( y = sqrt{x} + 9 )

Explanation:

Step1: Substitute x with 64

We know that \( x = 64 \), so substitute \( x \) into the equation \( y=\sqrt{x}+9 \). We get \( y=\sqrt{64}+9 \).

Step2: Calculate the square root

The square root of 64 is 8, because \( 8\times8 = 64 \). So now the equation becomes \( y = 8 + 9 \).

Step3: Add the numbers

Add 8 and 9. \( 8+9 = 17 \).

Answer:

17
