<h3>
Answer: 14 km per hour</h3>
=====================================================
Work Shown:
x = rowing speed when there is no current
c = speed of the current
speeds are in km per hour
-----------
Going downstream, i.e. with the current:
x+c = faster speed since the current is pushing you
distance = rate*time
d = r*t
40 = (x+c)*2
x+c = 40/2
x+c = 20
c = 20-x
-----------
Going upstream, i.e. against the current:
x-c = slower speed since the current is working against you
d = r*t
16 = (x-c)*2
16 = 2x-2c
2x-2c = 16
2(x-c) = 16
x-c = 16/2
x-c = 8
x-(20-x) = 8 ... plug in c = 20-x
x-20+x = 8
2x-20 = 8
2x = 8+20
2x = 28
x = 28/2
x = 14 km per hour is the rowing speed when there is no current
Side note: the speed of the current is c = 20-x = 20-14 = 6 km per hour.
Answer:
Step-by-step explanation:
1)
a) slope: 4/3
y-intercept: (0,-5)
equation: 4/3(x)- 5
b) slope: -1/2
y-intercept: (0, 1)
equation: -1/2(x)+ 1
2)
a) slope: 4/3
y-intercept: (0,2)
equation: 4/3(x)+ 2
b) slope: -3/2
y-intercept: (0,-3)
equation: -3/2(x)- 3
If Nicholas has 14 games, Daqauvion has 11 games because 14-3=11
Answer: E is located at (-2, 6)
Explanation:
The rule for reflecting over y = x is 
The x and y coordinates swap places.
Point E' is located at (6, -2) so that means point E must be located at (-2, 6)
