An exam worth 130 points has 32 questions. Each question is worth either 2 pt or 5 pt. You do all the 2 pt questions first to get them out of the way. Assuming you get all those 2 pt questions correct, how many of the 5 pt questions must you correctly answer in order to get at least 100 pt?

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

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 )
