James determined that these two expressions were equivalent expressions using the values of x = 4 and x = 6. Which statements are true? CHECK ALL THAT APPLY. a.7 x + 4 and 3 x + 5 + 4 x minus 1
b. When x = 2, both expressions have a value of 18.
c. The expressions are only equivalent for x = 4 and x = 6.
d. The expressions are only equivalent when evaluated with even values.
e. The expressions have equivalent values for any value of x.
f. The expressions should have been evaluated with one odd value and one even value.
g. When x = 0, the first expression has a value of 4 and the second expression has a value of 5.
h. The expressions have equivalent values if x = 8.

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.

4x and 6y

im not sure though

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
