<span>6 km × 1 hour/(b-4 km) = 12 km × (1 hour/(b+4 km)
6/(b-4) hours = 12/(b+4) hours
6(b+4) = 12(b-4)
6b + 24 = 12b - 48
72 = 6b
b = 12
The boat's speed in still water is 12 km/hour.</span>
Answer:
Its D thats the answer
Step-by-step explanation:
Answer:
A , B and E.
Step-by-step explanation:
the scientist can control and deal with the measure of manure that is given to a solitary corn plants. thus A is correct.
The reaction variable is the yield recorded for each plot due to the fact that the yield recorded in each plot is needed to check whether the compost is given or not. choice B is also correct
it's considered an experiment because the specialist is controlling the autonomous variable. then E is a right choice.
Answer:
The range of the function will be (- ∞, 4].
Step-by-step explanation:
See the graph attached.
Here we have to get the range of the graphed function.
The value of y in the graphed function varies in the range of less than or equal to 4.
Because the graph of the function does not move beyond 4 towards +∞.
Therefore, the range of the function will be (- ∞, 4]. (Answer)
Answer:
No Spaces - y=3x+4
Step-by-step explanation:
Using the format y= Mx+ b , m representping the slope and b representing the y intercept, the correct equation would be y = 3x + 4. Hope this helps : )
