Answer:

rivers speed( скорость потока)=1km/h

boats speed( скорость лодки)=11km/h

Step-by-step explanation:

скорость  лодки по течению=60/5=12km/h

скорость лодки против течения=60/10=10km/h

скорость лодки в стоящей воде=(12+10)/2=11km/h

скорость потока=1km/h

PLEASE ANSWER THIS ASAP !!!!
OLEGan [10]

Answer:

 -4

Step-by-step explanation:

Pick any two points, let's go with (-7, 21) and (-6, 17) to find slope:

slope m = (y₂ - y₁) / (x₂ - x₁)

             = (17- 21) / (-6 - (-7))

             = -4 / 1

         m = -4

---Extra info---

y-intercept using anyone point, let's use (-5, 13) and slope above:

  y = mx + b

  13 = -4(-5) + b

  13 = 20 + b

  b = -7

Equation of line:

y = mx + b

y = -4x - 7

Check:

(-7, 21)

  y = -4x - 7

  21 = -4(-7) - 7

  21 = 21

(-4, 9)

  y = -4x - 7

 9 = -4(-4) - 7

 9 = 9
