B is the answer to that question !!!
The time required for a race car to complete a 400 mile race is inversely proportional to the average speed that the car maintains. Express the relationship between race time and average speed in two equivalent forms.
The solution of a system of linear equations is the point where the two lines meet. Note that for the given equations, both lines have the same slope (4/5). If two lines have the same slope, it means that those lines are parallel. Parallel lines do not meet at any point, they stay parallel to the infinite.
Therefore, since this two lines are parallel, they don't meet and the system has no solution.
Answer:
Exponential Decay
Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
Step-by-step explanation:
We can graph the function by graphing two points when x=0 and x=1.
x=0 has
x=1 has y=
This function starts with higher output values and decreases over time. This is Exponential Decay. Its end behavior on the left is as follows as x approaches negative infinity y approaches positive infinity. Its end behavior on the right is as follows as x approaches positive infinity y approaches negative infinity.
