Answer:
k=3
Step-by-step explanation:
The given system of equations are
We need to find the value of k if the given system of equation have infinite number of solutions.
If two equations and have infinite number of solutions, then
Using this we get
Therefore, the value of k is 3.
8000 + 300 + 70 + 4 + 0.2 + 0.01
The answer should be 15 miles per hour.
