12. Carmen multiplied a non-zero rational number by its additive inverse. Which statement about the product must be true?

nignag [31]

Answer:

Option C. The product was negative.

Step-by-step explanation:

Let the non-zero rational number is = $\frac{x}{y}$

So, its additive inverse = $-\frac{x}{y}$

The result of multiplication the non-zero rational number by its additive inverse = $\frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}$

We will check the options:

A. The product was the multiplicative inverse of the original number.

Wrong because the product = $\frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}$

B. The product was the additive inverse of the original number.

Wrong because the product = $\frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}$

C. The product was negative.

True

D. The product was positive.

Wrong because the product was negative.

So, the answer is option C.

X+4y=30 system by substitution X-2y=0

Dmitry [639]

Answer:

x=10, y=5

Step-by-step explanation:

For substitution, you always want to get the variable alone. The second equation (x-2y=0) will be easier to substitute into the first equation.

x-2y=0

x=2y

You can substitute 2y as x on the first equation (x+4y=30).

2y+4y=30

6y=30

y=5

Plug y=5 into any equation.

x+4(5)=30

x+20=30

x=10
