Answer and Step-by-step explanation:
A) False, take (1,-1) and (1,1) both in V, but the sum (2,0) is not
B) True, if A,B are symmetric then A+kB is symmetric as well for k scalar, and zero matrix is symmetric.
C) True. The zero polynom is in V and P+kQ verifies (P+kQ)(0)=P(0)+kQ(0)=0
D) True. zero is solution and f+kg is since all coefficients are linear.
E) True, same than C)
F) False , the zero function doesn't verify that ( and the closure for sum will fail anyway 4+4=8)
G) False, the zero function fail to satisfy this ODE

The bigger triangle is 3 times larger than the smaller one
I’m pretty sure it’s this
Answer:
The absolute value inequality to represent the situation is presented as follows;
![\left | w -400 \right |](https://tex.z-dn.net/?f=%5Cleft%20%7C%20w%20-400%20%20%5Cright%20%7C%3C10)
Step-by-step explanation:
The given information are;
The number of words Annika needs to write = 400 words
The absolute deviation of the number of words Annika needs to write = 10 words
When we let the number of words Annika write = w, we have;
The absolute value inequality given that the absolute deviation of the number of words is 10 is given as follows;
Therefore we have;
gives the statement, -10 < w - 400 < 10.
Answer:
All triangles add up to 180 degrees
right angles are 90 degrees
we add 41 and 90 to find how many degrees are already there
41 + 90 = 131
we need 180 degrees so we see how many degrees are left
180 - 131 = 49
49 degrees are left so 49 is the answer because 49 finishes the triangle
