Sketch each collection of tiles below. name the collection using a simpler algebraic expression, if possible. if it is not possible to simplify the expression, explain why not. a. (-2x) + 5 + 3x - 4x + (-1) + (-x). b. six plus four times a number, plus four minus four times the number. c. three groups of a number plus two.
d. 5+7x^2+4x e. 4x^2−2x^2+(−6)+3

answer:

is option c

step-by-step explanation:

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.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
