Very simple. You just use the vectors as normal numbers, and multiply the coordinates with 2 and 4 like this:
2*u = 2* (2,4) = (4,8)
4*w = 4* (-1,3) = (-4,12)
(4,8) - (-4,12) = (8,-4)
So the vector has the coordinates (8,-4)
Answer:
-9
Step-by-step explanation:
you're taking away 7 each time, so -2-7=-9
Answer:
The answer is C
Step-by-step explanation:
We have f(x) function as below:
and the converted function g(x) is as mentioned below:
We can observe that:
f(x)=-g(x)
Therefore it can be said that this function reflected horizontally.
