When solving the equation 3(2x+6) +8=15, Rose wrote 3(2x+6)=7 as her number one step. Name
the property and explain why you think it is that property.

see below

Step-by-step explanation:

3(2x+6) +8=15

Subtract 8 from each side using the subtraction property of equality

3(2x+6) +8-8=15-8

3(2x+6) =7

That property is the Associate Property.

Step-by-step explanation:

I think that because Rose moved 8 to the other side of the equation for her first step, so that is why I think this is the answer.

the right system of equations to describe the situation would

be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of imogene and her

friend respectively at the end of t years.

now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

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.
