Answer: 
=========================================================
Explanation:
Use the pythagorean trig identity 
and plug in the fact that 
Isolating sine leads to 
. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
Answer:
There are no solutions.
Step-by-step explanation:
add the like terms
then the distribute the 5 and 8
subtract from both sides
then you will see the answer is no solutions
The equation is: 27.46 = 1.95x + 2.50
The answer is 12.8

The correct answer is
In fact, this is a trinomial of the form
, whose solutions are given by
Using this formula for the trinomial of the problem, we find:
<span>we see that this trinomial has two coincident solutions (x=3 with multiplicity 2). This means that it can be rewritten as a perfect square, in the following form:
