Answer:
The cost of hamburger is $1.75.
The cost of hot dog is $1.25
Step-by-step explanation:
Consider the provided information.
Seven hot dog (s )and two hamburger (s )cost $12.25;
Let the cost of hot dog is x.
The cost of hamburger is y.
Therefore,
......(1)
Two hot dog (s )and seven hamburger (s )cost $14.75.
......(2)
Use elimination method to solve the above equation.
Multiply equation 1 by 2 and multiply equation 2 by 7 and subtract them as shown:
Hence, the cost of hamburger is $1.75.
Now substitute the value of y in equation 1.
Hence, the cost of hot dog is $1.25
Answer:
Step-by-step explanation:
<u>Differentiation</u>
We have a relationship between x and y as follows:
Both variables depend on time t for t≥0.
Differentiating with respect to time:
Applying the derivative of a power function:
Recall the derivative of a constant is 0.
Dividing by 2:
Solving for y':
At some specific time, we have:
x=3, y=4, dx/dt = x' = 6. Substituting:
Operating:
Simplifying:
