ANSWER


EXPLANATION
We want to solve

where

We reciprocate both sides of this trigonometric equation to obtain:

We take arctangent of both sides to get;


This is the principal solution.
The tangent ratio is also positive in the third quadrant.
The solution in the third quadrant is

Answer:
x = 
Step-by-step explanation:
1. Move everything to one side of the equation.
x^2 - 19x - 1 = 0
2. Use the quadratic formula where a = 1, b = -19, and c = -1.
x = (-b +- sqrt(b^2-4ac)) / 2a
If you plug those numbers into that formula, you will get the result listed above
Answer:
y = 1/3x + 4
Step-by-step explanation:
The slope intercept form is y=mx+b so what we need to do is fill in the blanks. M is the slope and we know the 1/3 is the slope. (0,4) is basically meaning that the x-value is 0 and the y-value is 4, and when that's the case it means 4 is the y-intercept. Now we can put the information together y = 1/3x +4 is the equation.
Hope this helps and have a great day!
