Customers of a phone company can choose between two service plans for long-distance calls. The first plan has a $22 monthly fee and charges an additional $0.16 for each minute of calls. The second plan has a $28 monthly fee and charges an additional $0.11 for each minute of calls. For how many minutes of calls will the costs of the two plans be equal?

answer:

the position of equilibrium will shift to the left.

step-by-step explanation:

the general equation for the dissociation of a weak base is

b + h₂o   ⇌   bh⁺ + oh⁻

according to le châtelier's principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

if you apply a stress by adding more bh⁺ or oh⁻,   the system will respond by moving in a direction that gets rid of the added ions.

the position of equilibrium will shift to the left, forming more of the undissociated base.

answer: a

step-by-step explanation:

30,40,50 is correct answer

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
