24%

Step-by-step explanation:

Q: Maya has 200 songs on her mobile device. Of these songs, 48 are jazz songs. What percent of Maya's songs are jazz songs?

To find the percentage of something, we can take the number that we want to find the percentage for divided by the total number of items.

In this problem, the number that we want to find the percentage for are the jazz songs, which is 48.

The total number of items is 200 songs.

Therefore, we can divide the number of jazz songs by the total number of songs in order to find the percentage of Maya's jazz songs.

# jazz songs/total # songs 48/200 = 0.24

To convert a decimal to a percentage, we can move the decimal point two places to the right (aka multiply by 100).

0.24 → 24%

24% of Maya's songs are jazz songs.

(2x^2-x-6)/x^2-4

Factor top and bottom and you get

(2x+3)(x-2)/(x+2)(x-2)

The (x-2) cancel out each other leaving,

(2x+3)/x+2

The domain is all real numbers EXCEPT for -2. The domain can never be -2 as it would to the bottom having a zero, and that can't happen
