NEED HELP ASAP

Given the following vectors in component form:

u = ⟨10, 12⟩

v = ⟨– 3, y⟩



5u = ⟨50, 60⟩

5v = ⟨–15, 5y⟩



5(u + v) = ⟨35, 40⟩

What is the y-component of vector v?

y = –3
y = –4
y = –20
y = 4

Final answer:

The y-component of vector v is -3.

Step-by-step explanation:

To find the y-component of vector v, we can use the equation 5v = ⟨–15, 5y⟩ and compare it to the given component form of vector v, which is v = ⟨– 3, y⟩. By comparing the y-components of both equations, we can determine the value of y:

-15 = -3 * 5

From this, we can deduce that y = -3.
