Answer:
-15x<=45 and 14x<=-42
x>=45/-15 and x<=-42/14
x>=-3 and x<=-3
so x=-3

Answer:
The root of the equation 
is x ≈ 0.162035
Step-by-step explanation:
To find the roots of the equation you can use the Newton-Raphson method.
It is a way to find a good approximation for the root of a real-valued function f(x) = 0. The method starts with a function f(x) defined over the real numbers, the function derivative f', and an initial guess 
for a root of the function. It uses the idea that a continuous and differentiable function can be approximated by a straight line tangent to it.
This is the expression that we need to use
For the information given:
For the initial value you can choose 
although you can choose any value that you want.
So for approximation 
Next, with 
you put it into the equation
, you can see that this value is close to 0 but we need to refine our solution.
For approximation 
Again we put 
into the equation
this value is close to 0 but again we need to refine our solution.
We can summarize this process in the following table.
The approximation 
gives you the root of the equation.
When you plot the equation you find that only have one real root and is approximate to the value found.
YOU HAVE TO FIND THE SLOPE m
The formula to find the slope is m=(y₂-y₁)/(x₂-x₁)
Since we have the coordinate of each point, then we can calculate the slope m
7) (-6-3)/(2+4) = -9/6 =-3/2 (slope negative so the function falls
8) (-1-1)/(7-7) = -2/0 (tan ---> ∞ ) VERTICAL
9) (-2+2)/(5-3) = 0/2 = 0 slope = 0 ===> Horizontal
