Q:which equation illustrates the additive inverse? multiple choice?
Your instincts and logic are quite right! Trust yourself, you do good work!
Q:Do fuel additives Harm your engine?
Today's gasolines have additives in them. Using them are pretty much a waste unless you are trying to absorb water. All you would end up doing is putting deposits on your spark plugs.
Q:Additive inverse and mutiplicative inversre?
Additive inverse of 0.4 is -0.4, multiplicative inverse is 1/0.4 = 1.5. Additive inverse of -1.6 is 1.6, multiplicative inverse is 1/1.6 = 0.625 Additive inverse of 5 5/6 is -5 5/6, multiplicative inverse is 1/(5 5/6) = 1 /(35/6) = 6/35. (Do you see the pattern?) I hope that helps!
