Answer: 
which is Choice B
This is the same as writing 
The second "2" is not under or inside the square root.

Explanation:
Refer to the unit circle below. I've highlighted the angle 45 degrees and its corresponding sine value. It's the y coordinate of the point on the unit circle, for this particular angle.
Therefore, 
--------------
You could alternatively draw out a 45-45-90 triangle. Let x be the leg length and the hypotenuse is 1 unit long. Solve 
for x and you should get 
as the length of each leg.
Then take the ratio of the opposite over hypotenuse to find the same answer mentioned above.
Answer:
cost of tacos=$2
cost of soda=$1
Step-by-step explanation:
x=price of tacos
y=price of soda
3x+y=7 --> y=7-3x
4x+2y=10 --> y=5-2x
5-2x=7-3x
x=2
y=5-2(2)=1
Answer:
Step-by-step explanation:
If the tip varies directly with the number of guests, it means that an increase in the amount of tip would be as a result of an increase in the number of guests and a decrease in the amount of tip would be as a result of an decrease in the number of guests.
If we introduce a constant of proportionality, k , the relationship would be
t = kg
Given that
When t = 18, g = 10, then
18 = k × 10
k = 18/10 = 1.8
Therefore, the equation representing the relationship is
t = 1.8g
-6x -(3x)
Pretend that there is a -1 in front of the bracket
-6x-1(3x)
mutiply the bracket by -1
(-1)(3x)= -3x
-6x-3x= -9x
Answer: -9x
Your answer is False because obtuse angles are wide acute angles are right in the like this:^ but turn it to the west a right angle is like an L so your answer is False.
Your answer is False or B.
