Answer:

1)· 5x + 2y = 9. First we solve for y. 2y= 9 -5x. y=(9-5x)/2. Now that we have the value of y. We substitute on the original equation and resolve. 5x + 2y = 95x + 2y = 9 5x + 2(9-5x)/2 = 9 5x + 9 - 5x = 9 9 = 9

That would be x = 1

Now substitute and resolve to find y.

5(1) + 2y = 9

5 + 2y = 9

2y = 4

y = 2

So our answer x=1 and y = 2. (1,2)

Proof :

5(1) + 2(2) = 9

5+ 4 = 9

9 = 9

Answer:

$L\left(te^{2t }sin3t\right)=\frac{6s-12}{(s^2-4s+13)^2}$ .

Step-by-step explanation:

If F(s)= L{f(t)}

Then $L\left\{(t^nf(t)\right\}=(-1)^n\frac{\mathrm{d^n}F(s)}{\mathrm{d^n}s}$

$L\left\{te^{2t}sin3t\right\}$

f(t)= $e^{2t}sin3t$

$L\left\{e^{at}sinbt\right\}=\frac{b}{(s-a)^2+b^2}$

Therefore, $L\left\{e^{2t}sin3t\right\}=\frac{3}{(s-2)^2+(3)^2}$

$L\left\{e^{2t}sin3t\right\}=\frac{3}{s^2-4s+13}$

$L\left\{te^{2t}sin3t\right}=-\frac{\mathrm{d}F(s)}{\mathrm{d}s}$

=- $\frac{\mathrm{d}e^{2t}sin3t}{\mathrm{d}s}$

$L\left\{te^{2t}sin3t\right\}$

$=\frac{3(2s-4)}{(s^2-4s+13)^2}$

$L\left\{te^{2t}sin3t\right\}=\frac{6s-12}{(s^2-4s+13)^2}$ .
