Answer:
{5π/6, 11π/6}
Step-by-step explanation:
Since you have memorized the trig values of common angles, you know tan(π/6) = 1/√3, so cot(π/6) = √3.
The solution to this equation is ...
cot(θ) = -√3
so θ = -π/6 or, in the domain of interest, 11π/6. There is a corresponding quadrant II angle, 5π/6.
12,0

Answer:
x > 2
Step-by-step explanation:
y < 4x +3
y > -2x - 9
-2x -9 < 4x +3
-6x < -12
IN CASES WHERE YOU DIVIDE A NEGATIVE NUMBER,DON'T FORGET TO CHANGE THE SIGN !!!
x > 2
Answer:
35/4
Step-by-step explanation:
Change -1 2/3 into -5/3. Change -5 1/4 into -21/4.
Multiply -5/3 by -21/4= 105/12
Reduces down to 35/4
The least common denominator of 5/12 and -9/16
The answer is 48.
Now, we have to change the numerators also to make this a equal fraction to the first ones we had.
5*4 = 20
12*4 = 48
20/48
-9*3 = -27
16*3 = 48
-27/48
