Historians use terms such as a. d. or b. c., decade, and century to?

To be specific when identifying a certain time within our History. A.D., "Ano Domini" (i think thats how its spelle marks the years after the death of Christ, and B.C. means "Before Christ". These are used to help distinguish how long ago they were. The terms, such as "decades" and "centurys" are used to be shorter. So if you were writing a paper, instead of saying "545 years ago..." or if you dont know the exact years, you can simply put "centurys ago...".

hope this helps!!

d

step-by-step explanation:

an inequality is an expression which means more than one number is a solution. we graph the solutions on a number line to show all possible values. we graph using circles and arrows.

equal to and less/greater than are graphed with filled in circles on the value.only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.we draw an arrow the direction the solutions satisfy the inequality. generally this is the direction the inequality itself points.

this is a filled in circle on -2 so this is . this means only answers c and d are options.

answer d points to the right.
