Answer:
50 i - 41
Step-by-step explanation:
Simplify the following:
(-7 i + 8) (i - 6)
(8 - 7 i) (i - 6) = (8) (-6) + (8) (i) + (-7 i) (-6) + (-7 i) (i):
-6×8 + 8 i - 6 (-7 i) - 7 i×i
-6×8 = -48:
-48 + 8 i - 7 i (-6) - 7 i×i
-7 (-6) = 42:
-48 + 8 i + 42 i - 7 i×i
-7 i×i = -7 i^2:
-48 + 8 i + 42 i + -7 i^2
i^2 = -1:
-48 + 8 i + 42 i - 7-1
-7 (-1) = 7:
-48 + 8 i + 42 i + 7
-48 + 8 i + 42 i + 7 = (8 i + 42 i) + (7 - 48) = -41 + 50 i:
Answer: 50 i - 41
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.
4x+17+x+23+80=180. Now combine like terms.
5x+120=180
5x=60
X=12
Hello!
You solve this like an algebraic equation
You first distribute the 4 and 2
4x - 20 = 2x - 20 + 2x
Combine like terms
4x - 20 = 4x - 20
subtract 4x from both sides
-20 = 0x - 20
Add 20 to both sides
0 = 0
This means that there are infinite solutions to the equation.
Hope this helps!
