Hamburger Heaven is having a lunch special where customers buy one 4/3 -pound cheeseburger and get one free. If they set aside 48 pounds of meat, how many 3/4-pound cheeseburgers can they make?

answer:

your answer is: c. 196 7/8 in^3.

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 )

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
