Step-by-step explanation:
(x × 5) +6=41
5x + 6=41
5x =41-6
5x=35
x=(35/5)
x=7
Answer:
yes
Step-by-step explanation:
I would add like terms, meaning subtract 6.4 from both sides.
3.5n = 36.1
Answer:
x = $3, or x = $11
Step-by-step explanation:
The equation given is
where
- P(x) is the profit, and
- x is the app price
<u>We want app prices (x's) when profit (P(x)) is 0, so plugging in into the equation:</u>
![P(x)=-2(x-3)(x-11)\\0=-2(x-3)(x-11)\\0=(x-3)(x-11)](https://tex.z-dn.net/?f=P%28x%29%3D-2%28x-3%29%28x-11%29%5C%5C0%3D-2%28x-3%29%28x-11%29%5C%5C0%3D%28x-3%29%28x-11%29)
<em>It means (x-3) = 0 OR (x-11) = 0</em>
So, x = 3, or 11
