Selma wants to know if seventh grade students prefer to do their math homework in silence or with background music. she polled the 27 students in her music class. nine students preferred to do their math homework in silence, and eighteen students preferred to do their math homework with background music.

yes, because she picked people in music class who enjoy music

Step-by-step explanation:

She only asked people in music class, so that would mean that if your in music class people would probably like music,  but people who were not  in music might not like hearing background music

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )

answer: this is not a question
