Please help me

( Will give brainlst )

Step-by-step explanation:

You are given the equation for the number of times, y, that she visits them by distance x. You need only substitute the given x=4 into the equation y(x)

y=-3.5x+20, using x=4

y=-3.5(4)+20

y=-14+20

y=6

So we would expect her to visit her friend four miles away six times a month.

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.
