Q. Determine the value of y, if x is 16 .y=x−4Answer: y=
Substitute x value: Substitute the value of x into the equation.We are given that x=16, and we need to find the value of y from the equation y=x−4.Substitute x with 16: y=16−4.
Calculate square root: Calculate the square root of 16. The square root of 16 is 4, since 4×4=16. So, y=4−4.
Subtract to find y: Subtract 4 from 4 to find the value of y. Perform the subtraction: y=4−4=0.
