The idea is to replace every "x" by "3", and then do the calculations.
That factors to 5(x - 4)(x + 4)(x2 + 16)
5x - 8 = 717 5x = 725 x = 725/5 x = 145
x= -11
It is: y = -1/5x-2
7-5x=10-(6x+7) 7-5x=-60x-70 +5x +5x 7=-55x-70 +70 +70 77=-55x Divide -55 -1.4 = x

X= 2!
which of the following is a factor of x2 - 5x - 6
5/2
5x - 8 = 717 5x = 725 x = 725/5 x = 145
x= -11
If you mean: 5x/7 -6 = x then x = -21
It is: y = -1/5x-2
(2x - 7)(x + 1)
x=0
Slope = 5/3 = 1.66...
