Determine the value of y, if x is 9. y=|x|-5 Answer:

Substitute x = 9: Substitute the given value of x into the expression. We are given x = 9, so we substitute 9 for x in the expression y = |x| - 5. y = |9| - 5Evaluate absolute value: Evaluate the absolute value of x. The absolute value of a positive number is the number itself, so |9| = 9. y = 9 - 5Subtract 5: Subtract 5 from the absolute value of x. Now we perform the subtraction to find the value of y. y = 9 - 5 y = 4

Q. Determine the value of

y

, if

x

9

\newline

y=|x|-5

\newline

Answer:

Substitute $x = 9$ : Substitute the given value of $x$ into the expression. $\newline$ We are given $x = 9$ , so we substitute $9$ for $x$ in the expression $y = |x| - 5$ . $\newline$ $y = |9| - 5$
Evaluate absolute value: Evaluate the absolute value of $x$ . The absolute value of a positive number is the number itself, so $|9| = 9$ . $y = 9 - 5$
Subtract $5$ : Subtract $5$ from the absolute value of $x$ . Now we perform the subtraction to find the value of $y$ . $y = 9 - 5$ $y = 4$
