What property is demonstrated 4/5+(-4/5)=0

 is the ADDITIVE INVERSE of

and  is the ADDITIVE INVERSE of

Step-by-step explanation:

A number P is said to be the ADDITIVE INVERSE of the quantity Q

if and only if P  + Q   =    0

or if sum of any two terms is equivalent to 0, then they are additive inverse of each other.

here, P is the additive inverse of Q.

and   Q is the additive inverse of P.

Now, here given :

It implies by the definition of additive inverse  that:

 is the ADDITIVE INVERSE of

and  is the ADDITIVE INVERSE of

answer: no, but if it does it's a obvious pattern.

step-by-step explanation:

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
