Question

Evaluate the following expression: (1,4) - 5(1,1). Enter your answer as a vector.

Answer 1

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)
