If u = (1,3) and v=(2,6) find u + v

Alchen [17]

Answer:

Third option <3, 9>

Step-by-step explanation:

u and v are two vectors and we know the Cartesian components of these vectors.

We must find the sum of u + v.

If we have the Cartesian components of both vectors then the sum of both is done by adding the components of u with the components of v.

$u = \\v =$

$u + v = (1 + 2) i + (3 + 6) j$

Where i is the vertical component and j is the horizontal component

Then u + v is

$u + v = (3) i + (9) j$

$u+v =$

-3x-3y=3<br> y=-5x-17 <br> Substitution<br> Plz help if you can I would appreciate it

arsen [322]

First substitute the second equation into the first one:
-3x - 3(-5x - 17) = 3
Next distribute the parenthesis:
-3x + 15x + 51 = 3
Then combine like terms:
12x + 51 = 3
Now subtract 51 from each side:
12x = 48
Lastly to get x, divide each side by 12:
x = 4
Now put this into the second equation:
y = -5(4) - 17
Multiply:
y = -20 - 17
And subtract:
y = -37
The solution is (4,-37). Hope this helps!
