Answer: x = -7
Step-by-step explanation: to do the problem -3x - 11 = 10, first separate the x from everything else, except the -3. To do this, you have to get rid of the 11, and since it is negative, you have to add it to both sides of the equation. This gets rid of the 11 on the left side, and adds 11 to the right side, making the right side equal 21. Last, divide -3 from both sides to get x on the left, and -7 on the right. This makes x = -7
Using the addition rule of the Sine function and the Cosine function, we obtain 
.
<h3>What are the formulas for (sin x + sin y) and (cos x + cos y)?</h3>
- The formula for the addition of two Sine functions (
) is 
. - The formula for the addition of two Cosine functions (
) is 
.
Given that
Then using the above formulas, we get:
(1)
(2)
Dividing the equation (1) by (2), we get:
(3)
Now, we know that 
.
Thus, using the above formula, we get from (3):
Therefore, using the addition rule of the Sine function and the Cosine function, we obtain .

Answer: wouldn't be 1608.5? let me know if im wrong.
V = πr^2 h= π · 8^2 · 8 ≈ 1608.49544
Answer:
312.5
Step-by-step explanation:
Since it is $250 plus 20 cents per poster, the equation is 0.20p+250. It is $1 per poster at store and you want to know when the cost is going to be the same so you set them equal to each other.
0.20p+250=p
250=0.80p
312.5=p
