Select all the relations that are functions (3,2),(-1,7),(-3,1),(0,9),(2,-4)

a. she will receive a refund of $278.

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

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 )
