8. Name the property illustrated by $b c + (- b c) = 0$

Short Answer

Expert verified

Name of the property illustrated isAdditive Inverse.

Step by step solution

- Write properties of real numbers

Properties of real numbers are written in following table:

For any real numbers a,b, and c:
Property	Addition	Multiplication
Commutative	a+b=b+a	$a 路 b = b 路 a$
Associative	$(a + b) + c = a + (b + c)$	$(a 路 b) 路 c = a 路 (b 路 c)$
Identity	a+0=a=0+a	$a 路 1 = a = 1 路 a$
Inverse	$a + (- a) = 0 = (- a) + a$	If $a 鈮� 0$ , then $a 路 \frac{1}{a} = 1 = \frac{1}{a} 路 a$
Distributive	$a (b + c) = a b + a c and (b + c) a = b a + c a$

- Substitution in given values

Substitute a for bc in given equation.

For a=bc

Multiply both sides by $- 1$

$\begin{matrix} (鈭� 1) 脳 a = (鈭� 1) 脳 b c \\ 鈭� a = 鈭� b c \end{matrix}$

Now equation becomes $a + (- a) = 0$

- Identify the property

From the table of properties of real numbers, $a + (- a) = 0$ is the property of inverse in addition

Thus, additive inverse is illustrated by given equation.
