Answer: 
Step-by-step explanation:
Given
The force between the two particles is inversely proportional to the distance between them

When the distance is 2 m, the force is 10 N. For 5 m distance, it is

Thus, the force between them is
Answer:
W= -2
Step-by-step explanation:
Simply the expression: 9(w – 4) – 7w = 5(3w – 2)
First step: 9w -36-7w = 15w-10
Second step: 2w-36=15w-10
Third step:-36+10=15w-2w
Fourth step:-26=13w
Fifth step: w=
Six step: w=-2
For this case it is observed that the border of the region is not dotted, then the inequality includes an equal.
Thus, we discard options C and D.
We substitute the point (0,0) and see if it is fulfilled:

It is fulfilled, so the correct option is A.
Answer:
Option A
The last two choices are appropriate.
Both give you f(1) = 7, f(2) = 9.50, f(3) = 12.00, ... as they should.
