In a first-class lever like a see-saw, the force (F) varies inversely with distance (d) from the pivot point, or fulcrum. On one side of the see-saw, a force of 12 N was applied at a distance of 3 m from the fulcrum. In order to balance the see-saw, how much force must be placed 4 meters from the fulcrum on the other side? Type answer as a whole number (no decimals, no units).

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.

step-by-step explanation:

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
