Answer:
Option D
Step-by-step explanation:
x is given to be 4 in this case, so all we would have to is plug it into the following function -
Through substitution, you would receive the following function -

Now the graph proves that this function is closer to 4, and thus proves that the y - coordinate is about 2 at the same time. However, the graph is cut off, so the limit doesn't exists.
Answer:
a= 31
b=92
c=44
Step-by-step explanation:
In the case that you presented, the ratio is
50/100 = (x1)^2 / (x2)^2
1/2 = (x1)^2 / (x2)^2
x1 : x2 = 1 : √2
^2 means squared
1) 2x + 9 = 2x -5
9 ≠ -5 ; No solution
2) 2x- 1 = x + 3
x = 4; One solution x = 4
3) x + 2 = x + 2
0 = 0; Identity (or all real numbers)
ANSWER

EXPLANATION
We want to solve the trigonometric equation

We group like terms to obtain,

Divide both sides of the equation by 3 to get,

We can reciprocate both sides to get,

We simplify the right hand side to get,

Since the tangent ratio is negative, it implies that it is either in the second quadrant or fourth quadrant.
In the second quadrant,


In the fourth quadrant,
