Answer: 27 and -18
Step-by-step explanation:one positive and one negative number
7
Because if you look across from it its 7.
Answer:
![75\sqrt{2}(\sqrt{3}-1)](https://tex.z-dn.net/?f=75%5Csqrt%7B2%7D%28%5Csqrt%7B3%7D-1%29)
Step-by-step explanation:
In every right triangle, a leg is given by the multiplication of the sine of its opposite angle and the hypothenuse.
In this case, the opposite angle of x is 15°, and the hypothenuse is 300. So, we have
![x = 300\sin(15) = 75\sqrt{2}(\sqrt{3}-1)](https://tex.z-dn.net/?f=x%20%3D%20300%5Csin%2815%29%20%3D%2075%5Csqrt%7B2%7D%28%5Csqrt%7B3%7D-1%29)
Answer:
{-6, 12}
Step-by-step explanation:
Assuming that you meant (1/3), then you have:
(1/3)|3x - 9| - 5 = 4
First, let's combine the -5 and the +4:
(1/3)|3x - 9| = 9
Next, multipy both sides by 3 to eliminate the fraction 1/3:
|3x - 9| = 27
This absolute value equation has two separate parts:
3x - 9 = 27, and
-(3x - 9) = 27.
In the first case, we have x - 3 = 9, or x = 12.
In the second case, we have -3x + 9 = 27, or -3x = 18, or x = -6.
The solution set is {-6, 12}.
