Which choice provides an example of personification?
a) the door shut hard in my face.
b) the coke machine stole my money and taunted me with its loud hum.
c) i have to decide where to go for supper.
d) there is something odd about your new friend.

Personification is giving something non-human, human qualities. So the answer is A since the machine wouldn't literally be taunting them.

substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12     use distributive property

x + (2)(2x) + () = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20     divide both sides by 5

x = 4

put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
