Q. Evaluate the expression for r=−3r = -3.\newline∣−8−r∣=|-8 - r| = _____
  1. Plug in r=−3r = -3: First, let's plug in r=−3r = -3 into the expression.∣−8−r∣=∣−8−(−3)∣|-8 - r| = |-8 - (-3)|
  2. Subtract the numbers: Now, subtract the numbers, remember two negatives make a positive.\newline∣−8+3∣=∣−5∣|-8 + 3| = |-5|
  3. Find absolute value: Finally, the absolute value of –5–5 is just 55, cuz it's the distance from zero.\newline∣–5∣=5|–5| = 5
