Answer:
=7x^2+6x+6y-15
Step-by-step explanation:
Answer:
180< x < 270 so x is in 3rd quadrant ,hence tan x is positive cos x=-4/5 tan(x/2) = √ {(1 − cos x) / (1 + cos x)) = √ { (1+4/5)/(1–4/5) } =√{ 9/5)/(1/5) } =√9=±3 now ...
Answer:

Step-by-step explanation:
You have to solve for the x intercept on the equation

That is the x intercept for that equation.
Then solve for the y intercept on the equation

That is the x intercept for that equation.
Use that to find slope for point slope form

1 is the slope
and slope makes B the y intercept so the equation is
