Answer:
Commutative Property
Step-by-step explanation:
Commutative property, changes the order of the addends does not change the sum
Ex)
16+45=45+16
Here we want to find the equation of the line containing the median CP.
P, being the midpoint of AB can be found using the midpoint formula as:

.
The slope m of the line through CP can be found by the slope formula using points C(18, -8) and P(0, 1):

.
Now, we can write the equation of the line with slope -1/2, passing through
P(0, 1):

.
Answer:
No,

is not a subspace of

. A simple counter-example to the contrary: let

with

. However, scaling by -1 gives the vector

and

.
Answer:
Step-by-step explanation:
first add 3+5 = 8
then multiply 8 times x and 8 times -1
which is 8x-8
