hookes law gives the equation F=kx where F is the elastic force and k is the constant and x or small e is extension if we draw a graph you'll see that the graph increases by the same ratio every single time hence giving a straight line show that they are F and x are propotional to a certain limit
Answer=18
First step combine the positive like terms
16+8+6

30
Second step is to combine negative like terms with 30
30-3-9
When you do this you add 9 and 3 together since they are similar to each other so it equals 12 there for the equation becomes.....
30-12
Final answer 18
Answer:
I think it is the second one because -4 is the least
Step-by-step explanation:
First let's make both the miles and the hours ran improper fractions:

So, to find our miles per hour, we have to divide the miles by the hours to get: 
-9x=-36
divide both sides by -9
to get x by itself
to get +x
-9x/-9= -36/-9
cross out -9 and -9, then becomes -1*-1*x= x
x= -36/-9
answer:
x= 4
