Answer:
Graph C with the green dots.
Step-by-step explanation:
y = 0.5x + 5 is a linear equation, so we can rule out A because it is not straight.
5 represents the y-intercept, so we rule out B because that graph doesn't intercept the y-axis at (0,5).
Graph C represents a straight line that passes through (0, 5) & has a 0.5 slope, so that is our answer.
Hope this helps. :0)
 
        
             
        
        
        
Answer:
   232°
Step-by-step explanation:
There are a couple of ways to find the desired direction. Perhaps the most straightforward is to add up the coordinates of the travel vectors.
   30∠270° +50∠210° = 30(cos(270°), sin(270°)) +50(cos(210°), sin(210°))
   = (0, -30) +(-43.301, -25) = (-43.301, -55)
Then the angle from port is ...
   arctan(-55/-43.301) ≈ 231.79° . . . . . . . 3rd quadrant angle
The bearing of the ship from port is about 232°.

<em>Comment on the problem statement</em>
The term "knot" is conventionally used to indicate a measure of speed (nautical mile per hour), not distance. It is derived from the use of a knotted rope to estimate speed. Knots on the rope were typically 47 ft 3 inches apart. As a measure of distance 30 knots is about 1417.5 feet.
 
        
             
        
        
        
Answer:
the answer is 3 because 2a-2a+6a-2+2+2
2a-2a=0
6a-2+2+2=
6a-6
a= 3
