Answer:
A. 
B. 
and
D. 
Step-by-step explanation:
A rational function is of the form 
where
and 
are polynomial functions.
Based on this definition, every polynomial function is a rational function.
Hence the rational functions in the options provided are;
A.
B.
and
D.
is not a rational function because the numerator is not a polynomial function.
Answer:
x=1/2, y=4
Step-by-step explanation:
Double both sides of the top equation:
4x+6y=26
Now subtract boths sides of the second one from the first one:
(4x+6y) - (4x-y) = 26 - (-2)
7y = 28
so y = 4
4x-y=-2 so 4x-4=-2
4x=2
x=1/2

Answer:
P (factors of 12) = 5/6
Step-by-step explanation:
The possibilities are 1,2,3,4,5,6
Factors of 12 are 1,2,3,4,6,12
So out of the possibilities rolled
1,2,3,4,6 are factors of 12 (5 of the 6)
P (factors of 12) = 5/6
Answer:
y = (1/3)x^3 +4x + c . . . . . for some constant c
Step-by-step explanation:
The anti-derivative of x^n is (x^(n+1))/(n+1). Applying this rule to each of the terms in dy/dx, we get ...
y = (1/3)x^3 + 4x
There may be an added constant as well, conventionally represented by "c".
y = (1/3)x^3 +4x +c
