Answer: x = 2
Step-by-step explanation:
5x + 11 - 2x = 17
Combine like terms
3x + 11 = 17
Subtract 11 from each side
3x = 6
Divide each side by 3
x = 2
Answer:
Step-by-step explanation:
Locate the decimal point.
Count to the left of the decimal point.
The number with the most number of digits is larger than the number with fewer digits.
437160 has six digits.
It is 10 times bigger then
43716 which only has 5 digits.
Answer:
2
Step-by-step explanation:do it on a piese of parer them it will make more sence
4/3 - (-3/4)
4/3 + 3/4
16/12 + 9/12
25/12 = 2 1/12

Answer:
(A) 
with 
.
(B) 
with
(C) 
with 
(D) 
with ,
Step-by-step explanation
(A) We can see this as separation of variables or just a linear ODE of first grade, then 
. With this answer we see that the set of solutions of the ODE form a vector space over, where vectors are of the form 
with 
real.
(B) Proceeding and the previous item, we obtain 
. Which is not a vector space with the usual operations (this is because 
), in other words, if you sum two solutions you don't obtain a solution.
(C) This is a linear ODE of second grade, then if we set 
and we obtain the characteristic equation 
and then the general solution is with , and as in the first items the set of solutions form a vector space.
(D) Using C, let be 
we obtain that it must satisfies 
and then the general solution is with , and as in (B) the set of solutions does not form a vector space (same reason! as in (B)).
