Y = -x + 3
y = 2x + 6

y=4

x=-1

Step-by-step explanation:

replace y

2x+6=-x+3

3x=-3

x=-1

y=2x+6

y=2(-1)+6

y=-2+6

y=4

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

the answer is b.)

< 1=< 2
