What are additive inverse properties?Include at least 5 mathematical examples of the additive inverse, performing any calculations to explain why it is an example of the additive inverse accurately and correctly.I only have 2 dollars left so yeah..

  1. Which gives the first two steps to evaluate 3-2(7+1)^2-1A.                 Subtract 2 from 3, add 7 plus 1B.                 Add 7 plus 1, multiply 2 times 8C.                 Add 7 plus 1, square 8 *This is the answer I picked*D.                 Add 7 plus 1, subtract 1 from 8. 2. Which of the following equalities are valid? Choose all that apply. A.     (3^2+4)-2=11*I picked this*B.     (3^2+4)-2=5C.     2*(3^2-1)=16*and picked this*D.     2*(3^2-1)=35 3. Which statement illustrates the identity property of multiplication?                 A.                 11x+0=11xB.                 11x+1x=12xC.                 11x*1=11x *I guessed this one*D.                 11x*0=0                 4. Which statement illustrates the identity property of addition?                  A.                 10x+1x=11xB.                 10x+0=10x *I guessed this one*C.                 10x*1=10xD.                 10x*0=0 5. Which values for x and y make the statement (x - 9)(y + 4) = 0 true?A.                 X=-9, Y=4B.                 X=9, Y=4C.                 X=-9, Y=-4D.                 X=9, Y=-4 6. Which values for a and b make the statement (a - 2)(b + 3) = 0 true?A.                 a = -2, b = 3B.                 a = 2, b = 3C.                 a = -2, b = -3D.                 a = 2, b = -37.
