Speed of the boat = u
speed of the current = v
in downstream,
u - v = 105/5
u - v = 21
in upstream
u + v = 105/7
u + v = 15
add both equations
2u = 36
u = 18
v = -3
so
speed of the boat = 18 km/h
speed of the current = 3 km/h
Answer:
(10,10)
Step-by-step explanation:
coordinates are (x,y)
x is horizontal(left and right), y is vertical (up and down)
going down 6 means subtracting 6 from the second number
lets reverse that to go up and add 6 back
4+6=10
so the original point was (10,10)
Answer:
c
Step-by-step explanation:
im pretty sure an additive inverse is just the absolute value
Given the function f, match the function g with a transformation of f.
f(x) = x2 + 1, g(x) = (x - 2)2 + 1
☆☆☆☆☆☆☆☆a) f(x + 2)
b) f(x) + 2
c) f(x) - 2
d) f(x - 2)
The transformation that occured was a horizontal shift to the right of all the x's.
