Question

I’m so confused with this!!!

Answer 1

When you multiply a vector by a scalar, you distribute the scalar to the vector's components:

`k\langle a,b\rangle=\langle ka,kb\rangle`

In this case,

`\mathbf u=\langle25,-30\rangle\implies-\frac25\mathbf u=\langle-10,12\rangle`

so the answer is G.
