Answer:
Slope is 5 and y intersept is 5over6
Step-by-step explanation:
Answer:
Your original answer is corrrect
Step-by-step explanation:
At X= -1, Y decreases and then it rises back to -1 and continues to increase
Let, the speed of boat = x
Speed of current = y
So, x + y = 280/7
x + y = 40 ---- first equation
x - y = 280/14
x - y = 20
x = 20 + y
Substitute this value of x in first equation,
20 + y + y = 40
2y = 40 - 20
y = 20/2
y = 10
Substitute this in first equation,
x + 10 = 40
x = 30
In short, Speed of Boat = 30 mph, & speed of current = 10 mph
Hope this helps!
