Answer:
x•x•y•y•y•3
Step-by-step explanation:
I think you would have to put it in expanded form so the answer I gave should be correct.
You are given the points (-1, 7) and (4, -1).
You can easily find the slope by using the formula
m = (y₂ - y₁)/(x₂ - x₁)
m = slope
(x₁, y₁) = (-1, 7)
(x₂, y₂) = (4, -1)
m = (-1 - 7)/(4 + 1)
m = (-8)/(5)
m = -8/5
The answer is:
A. -8/5
If you have some knowledge of complex numbers: This follows pretty much immediately from Euler's formula and DeMoivre's theorem,
(Euler)
(DeMoivre)
so that is the imaginary part of the expanded left hand side.
If that's unfamiliar to you, you can make use of several identities to expand :
(double angle sine)
(double angle sine and cosine)
(Pythagorean)
Answer:
The simplified form would ve -19 - 4x
Step-by-step explanation:
Before we combine anything, we first must expand the expression by distributing the -3 to the terms in the parenthesis.
-7 - 3(4 - 2x) - 10x
-7 - 12 + 6x - 10x
Now we can combine the terms with and without variables.
-19 - 4x
