Answer:
The rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
Step-by-step explanation:
Given that a motorboat travels 441 kilometers in 9 hours going upstream and 388 kilometers in 4 hours going downstream, to determine what is the rate of the boat in still water and what is the rate of the current, the following calculation must be performed:
Upstream = 441/9 = 49 km per hour
Downstream = 388/4 = 97 km per hour
(97 + 49) / 2 = X
146/2 = X
73 = X
97-73 = 24
49-74 = -24
Therefore, the rate of the boat in still water is 73 km per hour, and the speed of the current is 24 km per hour.
we are given
point (-8,-7) for f(x)
and we have to find point for f(x-4)
we know that
whenever we have f(x-a) , we always add 'a' to x-value
so, we will add 4 units to x-value
Here , we have
x-value is -8
so,
new x-value is -8+4=-4
so, we will get
point for f(x-4) will be (-4,-7).......Answer
Answer:
x = - 3
Step-by-step explanation:
Given
5x - 4 = x - 16 ( subtract x from both sides )
4x - 4 = - 16 ( add 4 to both sides )
4x = - 12 ( divide both sides by 4 )
x = - 3
