6. If b>6, then 3b + 3 could be A. 18 B. 19 C. 20 D. 21 E. 22

Gala2k [10]

Answer:

E. 22

Step-by-step explanation:

Hello!

We know that b>6, and we are asked to find the possible values for 3b + 3.

Let's directly substitute 6 for b:

3(6) + 3
18 = 3
21

Now, because b is greater than 6, and not equal to 6, any value greater than 21 will work.

The correct option is E. 22.

Answer:

Functions: y = -x + 11, y = 2x^2 - 6x + 4, y = 7

Not Functions: x = 3, x^2 + y^2 = 81, y^2 = -5x - 12

Find the general solution of the given differential equation. x dy dx − y = x2 sin(x) y(x) = Correct: Your answer is correct. Gi

trasher [3.6K]

Divide both sides by $x^2$ - note that this means we can't have $x=0$ :

$x\dfrac{\mathrm dy}{\mathrm dx}-y=x^2\sin x$

$\dfrac1x\dfrac{\mathrm dy}{\mathrm dx}-\dfrac1{x^2}y=\sin x$

Then the left side reduces to the derivative of a product,

$\dfrac{\mathrm d}{\mathrm dx}\left[\dfrac1xy\right]=\sin x$

$\dfrac1xy=\displaystyle\sin x\,\mathrm dx=\cos x+C$

$y=x\cos x+Cx$

This solution is continuous everywhere, but accounting for the singular point $x=0$ , the largest interval over which it is defined would be $(0,\infty)$ or $(-\infty,0)$ .
