The nth term of a sequence is n-4 a) Work out the first three terms of the sequence.
b) Work out the tenth term of the sequence.

Step-by-step explanation:

a) 1st term: 1-4= -3

2nd term: 2-4= -2

3rd term: 3-4= -1

b) FORMULA: a1 (n-1) d

a1 (first term): -3

d (difference): 1

-3 (n-1) 1

-3-1n-1= -1n-4

hope it helps! please make me brainliest..

Thank you! have a good day ahead ☺️

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

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.
