Profit = Revenue - Costs

P(x) = (-0.32x² + 270x) - (70x + 52)
P(x) = -0.32x² +270x -70x -52 . . . . . . . . eliminate parentheses
P(x) = -0.32x² +200x -52

Which of the following represents the additive inverse of 125? A. -(-125) B. 125 C. -125 D. 1/25
Elden [556K]

Additive inverse of 125 is – 125, option C is correct.

<u>Solution:</u>

Given that , a number is 125

We have to find the additive inverse for the above given number from the above given set of options.

Now, we know that, <em>sum of a number and its additive inverse equals to 0. </em>

So, let us check option by option.

<em><u>Option A:</u></em>

Given number is -(-125)

-(-125) ⇒ 125 + ( - ( - 125 ) )  

⇒ 125 + 125  

⇒ 250 ⇒ wrong option

<em><u>Option B:</u></em>

Given number is 125

⇒ 125 + 125 ⇒ 250 ⇒ wrong option

<em><u>Option C:</u></em>

Given number is -125

125 + ( - 125 ) ⇒ 125 – 125  ⇒ 0 ⇒ correct option

Hence, additive inverse of 125 is – 125, option C is correct

How is twelve divided by fifteen equal to eight.
alexira [117]
It isn't at all!

When dividing numbers, the easiest way is to imagine the values as a fraction, and then reduce that fraction. If it reduces to a core fraction (ones that you should know their decimal value without thinking), then you have your answer.

\frac{12}{15} =  \frac{4}{5} = 0.8

We simplified our fraction by dividing the numerator and denominator by 4, which left us with  \frac{4}{5}, which we know is equal to 0.8.

You may be confused thinking that 0.8 is the same as 8. 0.8 is actually a tenth of the value of 8. This makes them very different values.

Below, I have also included a picture to help you memorize your common/core fractions. I recommend learning these as they will help you get through all sorts of math, from Geometry to Calculus!
