Question

evaluate the following expression: 2(1,1) -4(0,1). enter your answer as a vector.

Answer 1

Answer:

The answer is (2,-2)

You just distribute the 2 into (1,1) and same with the -4 into (0,1) and add them together ‍

Step-by-step explanation:

Answer 2

ANSWER

$\binom{2 }{ - 2}$

EXPLANATION

We were given the vector equation:

$2 \binom{1}{1} ) - 4 \binom{0}{1}$

We perform the scalar multiplications first to get:

$\binom{2 \times 1}{2 \times 1} ) - \binom{4 \times 0}{4 \times 1}$

Simplify the components of each vector

$\binom{2 }{2} - \binom{0}{4}$

We subtract the corresponding components of the vector to get:

$\binom{2 - 0}{2 - 4}$

This simplifies to

$\binom{2 }{ - 2}$
