Q. Determine the value of y y , if x x is 77.\newliney=∣x∣+9 y=|x|+9 \newlineAnswer:
  1. Identify Given Values: Identify the given values and the expression to use.\newlineWe are given that xx is 77 and we need to find the value of yy using the expression y=∣x∣+9y = |x| + 9.
  2. Substitute Value of xx: Substitute the value of xx into the expression.\newlineSince xx is 77, we substitute 77 for xx in the expression to get y=∣7∣+9y = |7| + 9.
  3. Evaluate Absolute Value: Evaluate the absolute value of xx. The absolute value of 77 is 77, because 77 is already a positive number. So, ∣7∣=7|7| = 7.
  4. Perform Addition: Perform the addition to find the value of yy.\newlineNow we add the absolute value of xx to 99: y=7+9y = 7 + 9.
  5. Calculate Final Value: Calculate the final value of yy. Adding 77 and 99 gives us y=16y = 16.
