Answer:
(im not sure what the first question is asking me)
Speed of the current is 2 miles per hour
Step-by-step explanation:
The reason the current is 2 miles per hour is because it when going down stream they were going 14 miles per hour, going upstream they went 10. The difference is 4mph. So if the current pushes you 2mph when going down stream and holds you 2 mph when going up, the constant speed is 12mph then you add and subtract 2 becuase of the two directions youre traveling. hence 10mph and 14mph.
Answer:
Step-by-step explanation:
y2-y1/x2-x1
-1-(-4)/3-7
3/-4
y=mx+b
For the y coordinate it can be either -4,or -1
-4=3/-4x+b
b=13/4
It would be A because everything is doubled
Answer: 1/4:1 1/4 = 2:b
↓
1/4 / 5/4 = 2/b
4/4 * 5 = 2/b
1/5 = 2/b
b/5 = 2
b = 2 * 5
b = 10
