the following sets are defined on the set of integers. U ={-5 < x < 10}, A= {x| -2< x < 5}, B= x|x < 6}, and C= {x| -3 < x < 5}. If A, B and C are subsets of U, list A intersection B intersection C

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1

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 )

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
