Q. Evaluate the expression for z=8.4z = 8.4.\newlineWrite your answer in simplest form.\newlinez−2−z+10=\frac{z - 2}{-z + 10} = __
  1. Substitute z=8.4z = 8.4: Substitute z=8.4z = 8.4 into the expression z−2−z+10\frac{z - 2}{-z + 10}.\newlineCalculation: 8.4−2−8.4+10\frac{8.4 - 2}{-8.4 + 10}
  2. Evaluate numerator: Evaluate the numerator 8.4−28.4 - 2.\newlineCalculation: 8.4−2=6.48.4 - 2 = 6.4
  3. Evaluate denominator: Evaluate the denominator −8.4+10-8.4 + 10.\newlineCalculation: −8.4+10=1.6-8.4 + 10 = 1.6
  4. Write fraction: Write the fraction with the evaluated numerator and denominator.\newlineCalculation: 6.41.6\frac{6.4}{1.6}
  5. Simplify fraction: Simplify the fraction by dividing both the numerator and the denominator by 1.61.6.\newlineCalculation: 6.41.6=4\frac{6.4}{1.6} = 4
