Answer:
A + B = 2κπ - C , κ∈Z or A + B = 2κπ + π + C , κ∈Z
Step-by-step explanation:
sin(A + B) = -sin C
sin(A + B) = sin( - C)
A + B = 2κπ + (-C) , κ∈Z or A + B = 2κπ + π - (-C) , κ∈Z
A + B = 2κπ - C , κ∈Z or A + B = 2κπ + π + C , κ∈Z
where:
- κ is an integer
- π is pi, the well known 3,14....
Step One: Plug in (x-1) for y in 2x-y = 0
Step Two: Distribute the negative
<u />
Step Three: Add like terms on one side of the equation
Step Four: Subtract 1 from both sides
Step Five: Plug x into one original equation (I chose y=x-1 but you can do either one)
That's the answer to the problem, x = -1, y = -2 (-1,-2)!
Hope this helps!
Answer:
KL = 7.8
Step-by-step explanation:
KH = HL
KH + HL = KL
3.9 + 3.9 = 7.8
Answer:
The domain of the function is
Step-by-step explanation:
Consider the provided rational function.
We need to determine the domain of the rational function.
Domain of a rational function is all real numbers except those for which the denominator is 0.
The denominator of the rational function is
From the above definition we know that:
That means for x=-3 the denominator is 0. Therefore, the domain of the function is all real number except -3.
Thus, the domain of the function is
Answer:
PR = PQ and ST = UT.
If this is not correct then:
PR = 8 ans UT = 2z+3
