Answer:
a) Figure attached
b)
Step-by-step explanation:
Part a
See the figure attached.
Part b
For this case first we need to find the vectors of velocity for the boat and the wind like this:
And now if we want to find the resulting velocity we just need to add the vector:
And the resultant magnitude would be:
And if we want the resultant angle we can do this:

X = 3y - 6....so sub 3y - 6 in for x in the other equation
2(3y - 6) - 4y = 8
6y - 12 - 4y = 8
2y = 8 + 12
2y = 20
y = 20/2
y = 10
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x = 24
solution is (24,10)
Answer:
Step-by-step explanation:
Which is true about the solution to the system of inequalities shown?
y 3x + 1
y 3x - 3
Only values that satisfy y 3x + 1 are solutions
Only values that satisfy y 3x3 are solutions
Values that satisfy either y a 3x + 1 orys 3x - 3 are solutions
Answer: y=5x/2 - 2.5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-2.5-2.5)/(0-2)
m=-5/(-2)
m=5/2
y=mx+b
y=5x/2 + b
-2.5=5(0)/2 + b
-2.5=0 + b
b=-2.5
y=5x/2 - 2.5
