Solve for x. 25 - 3x = -5(1 - x) - 2x
grandymaker [24]

Answer:

x = 5

Step-by-step explanation:

25 - 3x = -5(1 - x) - 2x

<u></u>

<u>We have to first get rid of the parenthesis:</u>

-5 * 1  ==>  -5

-5 * -x  ==>  5x

<u>So now you should have:</u>

25 - 3x = -5 + 5x - 2x

<u>Combine like terms:</u>

25 - 3x = -5 + 5x - 2x

25 - 3x = -5 + 3x

<u>Add 3x to both sides:</u>

25 - 3x  =  -5 + 3x

    + 3x  =      + 3x

<u>And you should have:</u>

25 = -5 + 6x

<u></u>

<u>Add 5 to both sides:</u>

25 = -5 + 6x

+5 = +5

30 = 6x

<u>Divide 6 to both sides:</u>

\frac{30}{6}     =      \frac{6x}{6}

5 = x

What does it mean for a differential equation to be autonomous?
andrew11 [14]
The term "autonomous" refers to an ordinary differential equation that relates the derivatives of the dependent variable as a function *only* of the dependent variable. In other words, the ODE doesn't explicitly depend on the independent variable.

Examples:

y'=y^2-1 is autonomous

y'=y^2-1+x is *not* autonomous

Write the equation for a parabola with a focus at (-8, -1) and a directrix at y = − 4.
Sidana [21]

Answer:

y = 1/6 x^2 + 8/3 x + 49/6

Step-by-step explanation:

This is a parabola which opens upwards.

The distance of a point (x, y)  from the focus is

√[(x -  -8)^2  + (y - -1)^2] and

the distance of the point from the line y = -4

= y - -4

These distances are equal for a parabola so:

√[(x -  -8)^2  + (y - -1)^2] = y + 4

Squaring both sides:

(x + 8)^2 + (y + 1)^2  = (y + 4)^2

x^2 + 16x + 64 + y^2 + 2y + 1 = y^2 + 8y + 16

x^2 + 16x + 64 + 1 - 16 = 8y - 2y

6y = x^2 + 16x + 49

y = 1/6 x^2 + 8/3 x + 49/6 is the equation of the parabola.
