We want to divide , i.e. .
So, assume that we have a number such that
This implies that
Those two expression are equal if the correspondent coefficients are equal:
And it should be immediate to conclude the value for k from here.
Velocity Against Current = 108 / 3 = 36 km/hour
Velocity With Current = 108 / 2 = 54 km/hour
"vsw" means velocity in still water "cs" means current speed
vsw -cs = 36
vsw +cs = 54 Adding both equations
2 * vsw = 90
velocity in still water = 45 km/hour
current speed = 9 km/hour

The graph of function f(x) and g(x) is parallel lines separated by 1 unit.
In this question we have been given two functions f(x) = - 3x + 4 and g(x) = f(x) + 1
We need to graph these functions and then describe the graph.
The graph of given functions is as shown below.
The graph of function f(x) is a straight line with slope -3 and y-intercept 4.
The function g(x) is nothing but but function f(x) translated upward by 1 unit.
The graph of function g(x) is also a straight line with slope -3 and y-intercept 5.
Therefore, the graph of function f(x) and g(x) is parallel lines separated by 1 unit.
