Full solution

Q. Determine the value of y y , if x x is 30-30 .\newliney=x+31 y=\sqrt{x+31} \newlineAnswer: y= y=
  1. Substitute xx with 30-30: To find the value of yy, we need to substitute xx with 30-30 into the equation y=x+31y = \sqrt{x + 31}.\newliney=30+31y = \sqrt{-30 + 31}
  2. Perform addition inside square root: Now, we perform the addition inside the square root. y=1y = \sqrt{1}
  3. Calculate final value of yy: The square root of 11 is 11, so yy equals 11.\newliney=1y = 1
