1 + 3i, - sqrt 10 would be the other two answers
Answer: 4.5y
Step-by-step explanation: You have To Multiply 15 times 0.3 and you get 4.5y
It could be 400,000 or 383,000
Answer:
A.28
Step-by-step explanation:
Substitute a with 28 so:
-6+28=22
Then simplify the equation:
22=22
Step-by-step explanation:
We want to find two things-- the speed of the boat in still water and the speed of the current. Each of these things will be represented by a different variable:
B = speed of the boat in still water
C = speed of the current
Since we have two variables, we will need to find a system of two equations to solve.
How do we find the two equations we need?
Rate problems are based on the relationship Distance = (Rate)(Time).
Fill in the chart with your data (chart attached)
The resulting speed of the boat (traveling upstream) is B-C miles per hour. On the other hand, if the boat is traveling downstream, the current will be pushing the boat faster, and the boat's speed will increase by C miles per hour. The resulting speed of the boat (traveling downstream) is B+C miles per hour. Put this info in the second column in the chart. Now plug it into a formula! <u>Distance=(Rate)(Time) </u>Now solve using the systems of equations!
