Answer:
A. False
B. True
C. False
D. True
Step-by-step explanation:
Only three dimensional subspace for R3 is R3 itself. In a 3 d subspace there are 3 basis vectors which are all linearly independent vectors. Dimension of a vector is number of subspace in that vector. Finite set can generate infinite dimension vector space.
Answer:
f(x) = 15
Step-by-step explanation:
"If f(x)= 5x + 40, what is f(x) when x = -5?"
Substitute x for -5:
f(x) = 5x + 40
f(x) = 5(-5) + 40
f(x) = -25 + 40
f(x) = 15
Answer:
4950
Step-by-step explanation:
first find the smallest multiple of 3 thats >100, 3*33=99, so 3*34=102 is the smallest multiple of 3 >100.
next find the greatest multiple of 3 <200, 3*66=198 which is the greatest multiple of 3<200
34-66+1=number of terms=33. then find the average of the terms: 102+198/2=150. 150*33=4950. the answer should be 4950
949 rounded to the nearest ten would be 950 because 5 and above rounds up to the next 10.

Let's simplify step-by-step.
−x2+2x−2x2−3x+4+x2
=−x2+2x+−2x2+−3x+4+x2
Combine Like Terms:
=−x2+2x+−2x2+−3x+4+x2
=(−x2+−2x2+x2)+(2x+−3x)+(4)
=−2x2+−x+4
Answer:
=−2x2−x+4
