A bottle shampoo costs $8.40 for a 24-ounce bottle. How much would a bottle with 36-ounce bottle cost at the same store? asap thanks

8.40 / 24 = 0.35 (cost per 1 ounce)

36 x 0.35 = 12.6 (cost for 36-ounce bottle)

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 )
