Gerri spent 1/21 of her money on pencils and 2/21 on paper. what fraction of money does she spend? give the answer in simplest form.

just add

1/21 + 2/21 =

3/21 (your answer)

you can semplify to:

1/7

the answer

b. they are parallel and will never intersect.

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 )
