Use the point slope formula. then, substitute the values inside the formula.
x1 =3
y1= -2
m = 23
y -y1 = m ( x - x1)
y - (-2) = 23 (x - 3)
y + 2 = 23 ( x - 3)
N= x+15 where n = nina, x = the amount hiked together and the 15 is how much she already walked.
Answer:
Speed of boat in still water is 6km/h
Speed of current is 4km/h
Step-by-step explanation:
We know speed = distance / time
Let the speed of boat in still water be x
Let the speed of current be y
Hence the speed of boat, down stream = 
Distance downstream = 20km
Time taken = 2 hours
We have
......(1)
Speed of boat upstream = 
Distance upstream = 4
Time taken = 2
We have
...(2)
Adding (1) & (2)
Substituting in (1) we get

Answer:
(13+x)cm
Step-by-step explanation:
Given data
Length of sides
1cm, 5cm, 7cm
Since the shape is four-sided and the fourth side is not given, let the fourth side be x
so
The perimeter of the polygon is
P= 1+5+7+x
P= 13+x
Hence the perimeter of the polygon is
P= (13+x)cm
