Q. Determine the value of y y , if x x is −12-12 .\newliney=x2−10 y=x^{2}-10 \newlineAnswer:
  1. Substitute xx in equation: Substitute the value of xx into the equation.\newlineWe are given x=−12x = -12 and the equation y=x2−10y = x^2 - 10. We need to substitute −12-12 for xx in the equation.\newlineCalculation: y=(−12)2−10y = (-12)^2 - 10
  2. Calculate square of −12-12: Calculate the square of −12-12. The square of −12-12 is 144144 because (−12)×(−12)=144(-12) \times (-12) = 144. Calculation: y=144−10y = 144 - 10
  3. Subtract 1010 from 144144: Subtract 1010 from 144144.\newlineNow we subtract 1010 from 144144 to find the value of yy.\newlineCalculation: y=144−10=134y = 144 - 10 = 134
