Step-by-step explanation: If f(x) = 4x + 10, then f(-2) is 4(-2) + 10
which simplifies to -8 + 10 or 2.
So f(-2) = 2.
V=1/3Bh
=1/3(230*230)(138)=2433400

Answer:
B is correct
Step-by-step explanation:
The person is mentioned is Phil. His amount of money and number of miles are proportionally related (Clark's amount of money and number of miles are not proportionally related due to initial donation)
For Phil, y = ax is his model.
Look into the graph, we can see there is a point where y = 30 and x = 4.
Then rate = 30/4 = 7.5
