Aschool district has 2 teaching positions to fill and there are 8 applicants to choose from how many different possibilities are there .

28 ways to fill the 2 positions

Step-by-step explanation:

There are 8 people who can fill the first position and then there are 7 people who can fill the second position (since the first position is filled)

8 * 7 = 56

But order does not matter, so we divide by  the number of positions

56/2 =28

d. vertex

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 )
