Determine the value of y, if x is 12 . y=|x-7| Answer:

Given x value: We have: x = 12 Identify the expression y = |x - 7| after substituting the value of x. Substitute 12 for x in y = |x - 7|. y = |12 - 7|Identify expression: y = |12 - 7| now becomes y = |5|. Simplify the expression inside the absolute value sign. |5| is the distance of 5 from zero on the number line. So, |5| = 5Substitute x in y: We found: y = |5| = 5 This is the final value of y when x is 12.

Q. Determine the value of

y

, if

x

12

\newline

y=|x-7|

\newline

Answer:

Given $x$ value: We have: $\newline$ $x = 12$ $\newline$ Identify the expression $y = |x - 7|$ after substituting the value of $x$ . $\newline$ Substitute $12$ for $x$ in $y = |x - 7|$ . $\newline$ $y = |12 - 7|$
Identify expression: $y = |12 - 7|$ now becomes $y = |5|$ . $\newline$ Simplify the expression inside the absolute value sign. $\newline$ $|5|$ is the distance of $5$ from zero on the number line. $\newline$ So, $|5| = 5$
Substitute $x$ in $y$ : We found: $y = |5| = 5$ $\newline$ This is the final value of $y$ when $x$ is $12$ .
