2. Lu's math score on her achievement test in seventh grade was a 700. Her math teacher told her that her test level went up by 25% from her
sixth grade test score level. What was Lu's test score level in sixth
grade?

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

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 )
