Choose the correct proportions.

15, 4, 12, 5

a) 4:5 = 12:15
b) 4:5 = 15:12
c) 5:4 = 12:15
d) 5:4 = 15:12

Solve the system. -a+4b+2c=-8 3a+b-4c=9 b=-1 a.(0,11) ,-1,2) c.(1,1,-2) d.(2,-1,-1)

Consider the table below. x y -1 -5 0 5 1 11 2 13 3 11 complete the standard form equation representing the quadratic relationship displayed above, where a, b, and c are constants.
