<u>ANSWER</u>

<u>EXPLANATION</u>
The given given equation is

We need to rewrite this equation in the slope-intercept form:

We add 3x to both sides.


We divide through by 2 to get,

The slope of this line is

Let the slope of the line perpendicular to this line be 'n' .
Then the product of the slopes of two perpendicular lines is always negative 1.




Therefore the slope of the new line is

C. If the first coefficient is negative, then the graph opens downwards
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:
A=8
Step-by-step explanation:
If you use the formula 30-60-90 which is a-radical 3a-2a
since the hypotenuse is 2a it equals 16
therefore if its 2a all you need to do is divide it where then you get 8.
