Answer:graph B
Step-by-step explanation:because if a line is parallel they have no solutions with a certain slope
If two lines intersect then they must have at least a solution
<span>1.66666666667 is the answer I swear man</span>
If
, then
and
because
lies in the fourth quadrant.
By DeMoivre's theorem,

so the answer is B.
Answer:
The resultant velocity will be 12m/s
Step-by-step explanation:
If the river flows downstream at 2m/s and also the boat is heading downstream at 10m/s. You can add the two velocities to get the resultant velocity:
Resultant Velocity = 10 m/s + 2 m/s = 12 m/s.
