Q. Determine the value of y, if x is 121.y=x+9Answer: y=
Substitute x in equation: We are given the equation y=x+9 and the value of x as 121. We need to substitute x with 121 in the equation to find the value of y.Calculation: y=121+9
Calculate square root: Calculate the square root of 121.Calculation: 121=11
Add 9 to find y: Add 9 to the square root of 121 to find the value of y.Calculation: y=11+9
Perform final addition: Perform the addition to get the final value of y.Calculation: y=20
