Answer:
18.50 times 3 equals 55.5, the answer is 55.50
Answer:
The lines are parallel
Step-by-step explanation:
x - y = 2
Solving for y
-y = -x+2
y = x -2
And the other equation is
y = x+1
These are both in slope intercept form
We notice that the slopes are both 1, but the y intercepts are different
That means the lines are parallel, but have different y intercepts

Answer:
The correct answer is marked.
Step-by-step explanation:
You are given the cosine of an angle, and asked to find the corresponding sine. The relation is ...
sin(x)² = 1 - cos(x)²
sin(x)² = 1 - (-4/√305)² = 1 - 16/305 = 289/305
sin(x) = √(289/305) = 17/√305
__
The arccos function will return an angle in the first or second quadrant. This negative cosine corresponds to a 2nd-quadrant angle. The sine is positive in the second quadrant.
