Power P = 11000 watt

We know that,

Joule :

Joule is the unit of SI system. Joule is the unit of energy.

Energy is the product of power and time.

1 J = 1 N-m

One watt is equal to the one joule per second.

Vaselesa [24]

Answer:

1.5y - 5

The solution system to 3y-2x=-9 and y=-2x+5
Alecsey [184]

Answer:

\boxed{(3,-1)}

Step-by-step explanation:

<em>Hey there!</em>

<em />

Well to find the solution the the given system,

3y - 2x = -9

y = -2x + 5

So to find x lets plug in -2x + 5 for y in 3y - 2x = -9.

3(-2x + 5) - 2x = -9

Distribute

-6x + 15 - 2x = -9

-8x + 15 = -9

-15 to both sides

-8x = -24

Divide -8 to both sides

<u>x = 3</u>

<u />

Now that we have x which is 3, we can plug in 3 for x in y = -2x + 5.

y = -2(3) + 5

y = -6 + 5

<u>y = -1</u>

<u><em /></u>

So the solution is (3,-1).

<em />

<em>Hope this helps :)</em>
