Hal makes an error when determining the difference quotient of f(x) = x2 + 11x + 2. His work is shown.

StartFraction ( (x + h) squared + 11 (x + h) + 2) minus (x squared + 11 x + 2) Over h EndFraction. StartFraction x squared + h squared + 11 x + 11 h + 2 minus x squared minus 11 x minus 2 Over h EndFraction. StartFraction h squared + 11 h Over h EndFraction. h + 11.

Which statement describes the error?

He did not expand (x + h)2 correctly.
He did not combine like terms correctly.
He should have subtracted f(x) – f(x + h), not
f(x + h) – f(x).
He should have added f(x + h) + f(x), not subtracted
f(x + h) – f(x).

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.

your answer is 228

step-by-step explanation:

add the top and bottom bases together, then divide them by 2, then multiply by the height.

(-5,-28)

parallel lines have the same slope. so if the green line has a slope of -4, the slope of the red line is also -4.
