Determine the value of y, if x is -9 . y=|x|+3 Answer:

Identify Absolute Value: Identify the absolute value operation in the equation. The equation y = |x| + 3 includes an absolute value operation, which means we take the non-negative value of x, regardless of its original sign.Substitute Value of x: Substitute the value of x into the equation. Since x is given as -9, we substitute -9 for x in the equation to get y = |-9| + 3.Calculate Absolute Value: Calculate the absolute value of x. The absolute value of -9 is 9, so the equation becomes y = 9 + 3.Add 3: Add 3 to the absolute value of x. Adding 3 to 9 gives us y = 12.

Answer:

Identify Absolute Value: Identify the absolute value operation in the equation. $\newline$ The equation $y = |x| + 3$ includes an absolute value operation, which means we take the non-negative value of $x$ , regardless of its original sign.
Substitute Value of $x$ : Substitute the value of $x$ into the equation. $\newline$ Since $x$ is given as $-9$ , we substitute $-9$ for $x$ in the equation to get $y = |-9| + 3$ .
Calculate Absolute Value: Calculate the absolute value of $x$ . The absolute value of $-9$ is $9$ , so the equation becomes $y = 9 + 3$ .
Add $3$ : Add $3$ to the absolute value of $x$ . $\newline$ Adding $3$ to $9$ gives us $y = 12$ .
