    For this case we have the following expression:

    (1, 4) - 5 (1, 1)

    The first thing we must do is multiply a scalar by a vector.

    For this, we make the distributive property in the second vector.

    We have then:

    (1,4) - (5,5)

    Then, we subtract vectors.

    For this, we subtract component to component.

    We have then:

    ((1-5), (4-5))

    (-4, - 1)

    Answer:

    The resulting vector is given by:

    (-4, - 1)
