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

What is the value of x in the diagram below?

Look at attachment. has all info needed. need
