The speed of the current is 7 mph. The boat travels three times slower against the current than with the current. What is the sp
kotykmax [81]
Let the speed of the boat be x
so going against the current the speed is x-7
going with the current the speed is x+7

let the distance be d
time = distance / speed
time to go against the current = d/(x-7)
time to go with the current = d/(x+7)

time going against the current is 3 times going <span>with the current
</span>
d/(x-7) = 3d/(x+7)     ⇒⇒⇒ divide by d 
1/(x-7) = 3/(x+7) 
x+7 = 3(x-7) 
x+7 = 3x - 21
2x = 28
x = 14

So, the speed of the boat in still water is = 14 mph

Write an equation of the line that passes through a pair of points:
vredina [299]

Answer:

b)

The  equation of the line that passes through a pair of points

   y  = \frac{-1}{8}  ( x ) -\frac{11}{8}

Step-by-step explanation:

 Explanation:-

Given points are ( 5 ,-2) and ( 3,-1)

slope of the line

                        m = \frac{y_{2} -y_{1} }{x_{2}-x_{1}  } = \frac{-1-(-2)}{-3-(5)} = \frac{1}{-8}

The  equation of the line that passes through a pair of points

              y - y_{1} = m ( x - x_{1} )

           y - (-2) = \frac{-1}{8}  ( x - (5) )

          y  = \frac{-1}{8}  ( x ) +\frac{5}{8} -2

        y  = \frac{-1}{8}  ( x ) +\frac{5-16}{8}

      y  = \frac{-1}{8}  ( x ) -\frac{11}{8}
