The equation y = -3x - 4 and another equation have a solution of (3,-13). Which of the following could be the second equation?

A. y= 2x - 19
B. y = 5x - 18
C. y = -2x + 12
D. y = -5x + 8

y = 2x -19

Step-by-step explanation:

Put 3 and -13 as values of x and y and see which equation remains true. i.e Left side - right side. That is your answer

Option A

y = 2x -19

Put values

-13 = 2 (3) -19

-13 = 6 - 19

-13 = -13

Rest of equations do not. You may check on your own so option A is answer.

(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
