Q. Determine the value of

y

, if

x

is

7

.

\newline

y=|x|-10

\newline

Answer:

Substitute $x$ into function: Substitute the value of $x$ into the function. $\newline$ We are given the function $y = |x| - 10$ and we need to find the value of $y$ when $x$ is $7$ . $\newline$ Substitute $x = 7$ into the function: $\newline$ $y = |7| - 10$
Calculate absolute value: Calculate the absolute value of $x$ . The absolute value of $7$ is $7$ , because $7$ is already a positive number. $y = 7 - 10$
Perform subtraction: Perform the subtraction to find the value of $y$ . $\newline$ Now we subtract $10$ from $7$ to get the value of $y$ : $\newline$ $y = 7 - 10$ $\newline$ $y = -3$
