Answer:
If I am understanding your question, the total upstream is 8 miles and another 8 miles downstream.
Let s = the speed of the boat in still water
d = rt
8 = 5(s + 3) downstream
8 = 5s + 15 equation 1
8 = 5(s - 3) upstream
8 = 5s - 15 Add equation 1
8 = 5s + 15
16 = 10s Divide both sides by 10.
s = 16/10 = 8/5 = 1.6 mph
x = -5 is the equation of the line that is parallel to the line x = –2 and passes through the point (–5, 4)
<em><u>Solution:</u></em>
Given that, we have to write the equation of line that is parallel to line x = -2 and passes through point (-5, 4)
From given,
The equation of the line in standard form is x = -2
<em><u>This is a vertical line, so the parallel line will also be a vertical line of the form:</u></em>
x = a
Since we are given that the line should pass through the point (-5, 4) then the equation of the line is:
x = -5
Thus the equation of line is found
