Answer:

x = -1/3

Step-by-step explanation:

x = [-6 +- squareRoot(36-4x9)] / 2 times (-6)

= -6/18 = -1/3

x-(-1/3) = 0 ---> x = -1/3

Answer:

x=\frac{-6\pm \sqrt{6^{2}-4(9)(1)}}{2*9}

Step-by-step explanation:

For this function [f(x)=9x²+6x+1], we'll solve it by the traditional way, via General Formula

9x^{2}+6x+1=0 \Rightarrow x=\frac{-6\pm \sqrt{6^{2}-4(9)(1)}}{2*9}\Rightarrow x=-\frac{1}{3}\Rightarrow S=\left \{ -\frac{1}{3} \right \}

Burka [1]
The answer is x=4. 
set the equations up: 8x-5=6x-3
Subtract 6x from one side and then the other side 2x-5=3 
Add 5 from one side and then the other 2x=8

Find the equation of the graphed line.?
kiruha [24]

Answer:

c.  y = x - 6.

Step-by-step explanation:

It's a straight line whose general form is y = mx + c.

The slope is (0, -6) / (6, 0)

= -6 / -6

= 1 so the coefficient of x , (m)  is 1.

The value of  c ( the y-intercept) is -6.
