Which polynomials are listed with their correct additive inverse? Check all that apply. X2 3x â€"" 2; â€""x2 â€"" 3x 2 â€""y7 â€
salantis [7]

Given to us:

(a)\ x^2+3x-2;\ -x^2-3x+2\\\\(b)\ -y^7-10;\ -y^7+10\\\\(c)\ 6z^5+6z^5-6z^4;\ (-6z^5)-(6z^5)+6z^4;\\\\(d)\ x-1;\ -x+1\\\\(e)\  (-5x^2) + (-2x) + (-10);\  5x^2 - 2x + 10

Additive inverse means changing the sign of the number and adding it to the original number to get 0(zero) as our answer.

(a)

x^2+3x-2;\ -x^2-3x+2)\\x^2+3x-2 +( -x^2-3x+2)\\ on solving this we will get zero.

hence, this is an additive inverse.

(b)

-y^7-10;\ -y^7+10\\-y^7-10+( -y^7+10)  on solving this we will not be getting zero.

hence, this is not an additive inverse.

(c)

6z^5+6z^5-6z^4;\ (-6z^5)-(6z^5)+6z^4,\\\\6z^5+6z^5-6z^4+[ (-6z^5)-(6z^5)+6z^4}  on solving this we will get zero.

hence, this is an additive inverse.

(d)

x-1;\ -x+1\\x-1+( -x+1)    on solving this we will get zero.

hence, this is an additive inverse.

(e)

-5x^2 + -2x -10;\  5x^2 (- 2x) + 10\\-5x^2 + -2x -10+ 5x^2 (- 2x) + 10  on solving this we will not be getting zero.

hence, this is not an additive inverse.

Law Incorporation [45]

Answer:

13 1/3 pounds

Step-by-step explanation:

Hi! Each bad weighs 2 2/3 pounds. There were 5 bags bought so we multiply. Here is the expression:

2 2/3 x 5 = x

Now we need to convert 2 2/3 into an improper fraction, which is 8/3.

Easy! Now

8          5         40

-      x    -     =    -

3           1          3

*I tried to set it up like fractions.*

Simplify 40/3 and you get 13 1/3
