Question

Properties if real numbers, find the additive inverse and multiplicative inverse of each number

Answer 1

#1

0.4

Additive=-0.4

Multiplicative=1/0.4

#2

5 5)6=35/6

• Additive=-35/6
• Multiplicative=6/35

#3

5x-3y-2x+3y=3x

• Additive=-3x
• Multiplicative=1/3x

#4

-11a-13b+7a-3b=-4a-16b

Additive

• 4a+16b

Multiplicative

• 1/(4a+16b)

#5

8x-7y-(3-6y)=8x-7y-3+6y=8x-y-3

Additive.

• y-8x+3

Multiplicative

• 1/(8x-y-3)
