4x+8y=-24
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
x = ¼x^4 + 4x + k where k can be any number
Re=Write as 16x^(3) + 12x^(2) + 4x Take out the common factor of '4' Hence 4(4x^(3) + 3x^)2) + x) Take out the common factor of 'x' Hence 4x( 4x^(2) + 3x + 1) The answer!!!!!
-2x = -4x + 24 2x = 24 x = 12
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
2
8x-1 = -4x+23 8x+4x = 23+1 12x = 24 x = 2
4x-14
(6, 0) and (0, 8)
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
