B is the correct answer to this question
X = 2
y = 1
You can get this by replacing the y in the second equation with the 3x - 5 from the first. Then solve for x. Once you have that value, you can solve for y.
Y=3(-3) x 2
y= -9 x 2
y=-18

Answer:
inequality- 1.29m <20
maximum number of songs- 15 songs
Step-by-step explanation:
For the inequality, you see that she only has $20 so whatever she buys has to be below that so use the less than sign. You also see that each song is worth $1.29 so 1.29m. For the maximum number of songs, you divide 20 by 1.29 and just ignore the remainder.
18a is correct, 18b is incorrect, 18c is correct, 18d is false, 18e is false, 18f is true, 19 is incorrect.
