The answer is 2.
Since you are subtracting C(x) from R(x), your equation would look like this.
P(x)=-.5x^2+800x-100-(300x+250)
which if you then simplify would be
P(x)=-.5x^2+500x-350
Answer:
yes it is
Step-by-step explanation:
it is quadrilateral
Answer:
<u>f</u><u>(</u><u>-</u><u>2</u><u>)</u><u> </u><u>+</u><u> </u><u>9</u><u> </u><u>is</u><u> </u><u>1</u><u>9</u>
Step-by-step explanation:
![f(x) = - 3x - 2](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%20-%203x%20-%202)
when x is -9:
![f( - 2) = - 3( - 2) - 2 \\ f( - 2) = 10](https://tex.z-dn.net/?f=f%28%20-%202%29%20%3D%20%20-%203%28%20-%202%29%20-%202%20%5C%5C%20f%28%20-%202%29%20%3D%2010)
sum up with 9, f(-2)+9:
![f( - 2) + 9 = 10 + 9 \\ = 19](https://tex.z-dn.net/?f=f%28%20-%202%29%20%2B%209%20%3D%2010%20%2B%209%20%5C%5C%20%20%3D%2019)
I have no idea but this was like forever ago so hope u got ur answers in time lol
Step 1: Set the equation equal to 0.
Do this by subtracting 6x from both sides and you get:
x^2 - 4 = 0
Step 2: Factor
This is a difference of two square. In general a^2 - b^2 factors as (a+b)(a-b).
In your equation:
(x+2)(x-2) = 0
Step 3: Break this apart into two separate equations.
If two factors multiply to make 0, one of them has to be zero. So set each one individually equal to 0.
x+2 = 0 OR x-2=0
Step 4: Solve each equation individually.
x+2 = 0
x = -2
x-2 = 0
x = 2
Step 5:
Check both solutions to make sure they’re correct.
