find the indicated vector.
let u = (-9,1), v=(-5,9). Find 3u+v
3u+v = 3(-9,1) + (-5,9) = (-27,3)+(-5,9) = (-32,12)
To find 3u+v, we need to multiply vector u by 3 and then add it to vector v.
First, multiply vector u by 3:
3u = 3 * (-9, 1) = (-27, 3)
Now, add vector v to the result:
3u + v = (-27, 3) + (-5, 9)
= (-27 + (-5), 3 + 9)
= (-32, 12)
Therefore, the indicated vector 3u + v is (-32, 12).
To find the vector 3u + v, we need to multiply the vector u by 3 and then add it to the vector v.
Given u = (-9, 1) and v = (-5, 9), we can first multiply u by 3:
3u = 3(-9, 1) = (-27, 3)
Next, we add v to the result:
3u + v = (-27, 3) + (-5, 9)
Adding the corresponding components, we get:
3u + v = (-27 - 5, 3 + 9) = (-32, 12)
Therefore, the vector 3u + v is (-32, 12).
