Q. Determine the value of y y , if x x is −9-9 .\newliney=∣x∣+3 y=|x|+3 \newlineAnswer:
  1. Identify Absolute Value: Identify the absolute value operation in the equation.\newlineThe equation y=∣x∣+3y = |x| + 3 includes an absolute value operation, which means we take the non-negative value of xx, regardless of its original sign.
  2. Substitute Value of xx: Substitute the value of xx into the equation.\newlineSince xx is given as −9-9, we substitute −9-9 for xx in the equation to get y=∣−9∣+3y = |-9| + 3.
  3. Calculate Absolute Value: Calculate the absolute value of xx. The absolute value of −9-9 is 99, so the equation becomes y=9+3y = 9 + 3.
  4. Add 33: Add 33 to the absolute value of xx.\newlineAdding 33 to 99 gives us y=12y = 12.
