1. What is the additive inverse of (x-2y) 2. What is the multiplicative inverse of (-x/2y )?
if a is the additive inverse of b then a + b 0 The additive inverse of x-2y is 0 - (x-2y) 2y-x If a is the multiplicative inverse of b, then ab 1 Not exactly sure what you mean by (-x/2y) Assuming omitted parentheses around the denominator, the multiplicative inverse of -x/(2y) is 1/(-x/(2y)) -2y/x Interpreted per PEMDAS rules, the multiplicative inverse of -x/2y -(x/2)y is 1/[(-x/2)y] -2/(xy)
Yes, increased pad life and no glazing rotors. I have seven years on a set for a Corolla and negligible wear from daily driving.
