Need ! 10 points! a home alarm system randomly assigns a four-character code for each person. the code will not repeat a character. the characters are 2, 3, 4, 5, m, v, t, or r. what is the total number of codes that can be randomly assigned? a. 6,720 codes b. 1,680 codes c.336 codes d. 20,160 codes

The answer is 1680. To get this you do 8*7*6*5 because there are 8 options for the first character, and then you can repeat that for the second one with 7, 6, and 5

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
