No.
The reason it's no is because y-x^2=9 is does not go through the the the y axis with a straight line. Instead, it goes through cricked. You have to have a better line to be able to have the yes option, if it was going straight through then it would be the correct answer.
A)
For x= -1
y=x^2-4x
y= (-1)^2 -4*(-1)
y= -3
For x=1
y = -3
For x=2
y =-4
For x=4
y= 0
B) the blue one
The answer is c hopefully it helps
You can proceed like this,
650 kb for a pic
and 2200kb for song ( 650 + 1550)
total= 18150 kb and 16 files
so, 650 kb each in both pic and song = 16 * 650= 10400
remaining = 18150-10400 = 7750 , which is contributed by additional 1550 of songs that is
7750/1550 = 5
so, a total of 5 songs and 11 pictures were sold..
hope it helped
