Answer:

<u>Option C. The product was negative.</u>

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.

<u>Wrong </u>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.

<u>Wrong </u>because the product = \frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}

C. The product was negative.

<u>True</u>

D. The product was positive.

<u>Wrong </u>because the product was negative.

<u>So, the answer is option C.</u>

If (a+10) and (a+20)are supplementary angles,find them​
motikmotik

Given:

(a+10) and (a+20) are supplementary

To find:

Each angle

Steps:

if 2 angles are supplementary that means they add up to 180°

(a + 10) + (a + 20) = 180

   a + 10 + a + 20 = 180

              2a + 30 = 180

                      2a = 180 - 30

                      2a = 150

                        a = 150/2

                        a = 75°

Now let's find value of each angle,

a + 10 = 75 + 10

          = 85°

a + 20 = 75 + 20

           = 95°

Therefore, the value of each angle is 85° and 95° respectively

Happy to help :)

Which ordered pair is the best estimate of the solution of the system 3x+y=4 x-3y=4?
vovangra [49]
3x+y=4\ \ \ \ \ \ ..............equation(1)\\x-3y=4\ \ \ \ \ \ ..............equation(2)\\\\ Using~equation~(2), \\\\&#10;x-3y=4\\x=4+3y\\\\Now,\ using\ the\ value\ of\ x\ in\ equation\ (1),\ we\ get,\\\\(4+3y)-3y=4\\\\4=4

Since all the variables cancel out and the coefficient equal to eachother, this system of equation has <u>infinitely many solutions!</u>
