Hi There!

The answer to your problem is A) 4

Move all terms containing x to the left, all other terms to the right

Add '-14' to each side of the equation.

 $14 + -14 + -1x = 10 + -14$ 

Combine like terms: 14 + -14 = 0 

 $0 + -1x = 10 + -14$ 

 $-1x = 10 + -14$ 

Combine like terms: 10 + -14 = -4

 $-1x = -4$ 

Get your answer

 $x = 4$ 

Hope This Helps!

Find the mean for the scores : 3810;5300;8540;4300,5340

Aleonysh [2.5K]

Answer: 5458

Step-by-step explanation: So the mean is the same thing as the average. To find the mean you add up all of the numbers, and then divide by 5 because there are five numbers. So the sum would be 27,290. Then that divided by 5 would be 5458.

A. Solve the differential equation <img src="https://tex.z-dn.net/?f=y%27%3D2x%20%5Csqrt%7B1-y%5E2%7D%20" id="TexFormula1" title

$y' = \frac{dy}{dx}$

seperable differential equations will have the form
$\frac{dy}{dx} = F(x) G(y)$

what you do from here is isolate all the y terms on one side and all the X terms on the other
$\frac{dy}{G(y)} = F(x) dx$
just divided G(y) to both sides and multiply dx to both sides

then integrate both sides
$\int \frac{1}{G(y)} dy = \int F(x) dx

$

once you integrate, you will have a constant. use the initial value condition to solve for the constant, then try to isolate x or y if the question asks for it

In your problem,
$G(y) = \sqrt{1-y^2}

F(x) = 2x$

so all you need to integrate is
$\int \frac{1}{\sqrt{1-y^2}} dy = \int 2x dx$
