Answer: 54-2y
Step-by-step explanation:
If x equals 18, you need to multiply 3 times 18. It would need to stay as an expression since they have different variables.
Answer:
I don't know if this is correct but wouldn't it be 560?
Step-by-step explanation:
If you have 10 on one side, you divide 10 by 1/4 to get 40. So you need 40 blocks to fill one side, and 3 1/2 on the other only needs 14. 14*40=560.
Given the position function
s(t) = 7 - 14t
The instantaneous velocity is the derivative the the position function:
s'(t) = v = - 14
The velocity in an instant in time is 14 m/s in the opposite direction.
