What system of equations is shown by the graph plsss help I have no idea how to do this without a calculator and the teacher didn’t let us bring ours home and I need help

y-x=15 and 25+2x=y

Step-by-step explanation:

we can figure out both of these have a positive slope, so we can rule out any option with an equation that has a negative, or slope of 0.

that means we can rule out 1 and 3.

The blue line looks like it has a y intercept of 15, and the only equation that has that is in option 2, which is y-x=15 and 25+2x=y

we can convert these to slope intercept form

so

y=x+15 and y=2x+25

you can double check your slope and y intercepts and will find that this is correct

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.

the 3rd on is correct
