Answer:
-5x+2
Step-by-step explanation:
1. Multiply number 2 and 2=4 so it is
4-5x-2
2. Combine like terms
-5x+4-2
3. Subtract the numbers
-5x+2
Using the identity:
, we get:
There are two solutions to this equation:
1) Since the period of cosine is 2π, so 0 + 2π = 2π will also be a solution to the given equation
2) Therefore, there are 3 solutions to the given trigonometric equation.
Answer:
n=−0.545455
Step-by-step explanation:
n(6.5)=−3+n
Simplify both sides of the equation.
n(6.5)=−3+n
6.5n=−3+n
6.5n=n−3
Subtract n from both sides.
6.5n−n=n−3−n
5.5n=−3
Divide both sides by 5.5.
5.5n
5.5
=
−3
5.5
