Answer:
The first statement.
Step-by-step explanation:
Because when you look at the July graph you can see that the highest number of miles is 15 and the lowest number of miles is 1 so the range is 15 - 1 = 14.
When you look at the August graph you can see that the highest number of miles is 13 and the lowest number of miles is 5 so the range is 13 - 5 = 8
So the range of the July month is greater than the range of the August month
Answer:
(1)
Multiplying by 3 both sides of the equality you get that
3u is in the Span of the vectors 
.
(2)
That's not true, consider the following counter example.
is a linear combination of 
but is NOT a linear combination of 
Step-by-step explanation:
(1)
As the hint indicates, you know that
Then, if you multiply both sides of the equality by 3, you get that
And that's it. 3u is in the Span of the vectors
(2)
That's not true, consider the following counter example.
is a linear combination of but is NOT a linear combination of
Divide subtract multiply addition
