Graph the following inequality and then select the correct graph below. x - y - 2 ≥ 0
2 answers:
Answer:
the graph in the attached figure
Step-by-step explanation:
we have
Isolate the variable y
-----> Multiply by
The solution of the inequality is the shaded area below the solid line
The equation of the line is
The slope of the line is positive
The y-intercept of the line is the point
The x-intercept of the line is the point
Using a graphing tool
the graph in the attached figure
To be able to graph any equation, simply solve for y.
You should get y ≤ x - 2
[the sign switched because you needed to divide by -1 in order to solve for y all the way]
Then use -2 as your y-intercept. This is the point that is at (0,y) on a graph. From the origin, just go down 2 points, and mark your point.
X is the same as 1/1 x. This is your slope. From point -2, <em>rise</em> 1 point, then <em>run</em> 1 point to the right (because it is positive). From that position, mark another point. You now have enough to make a line, which gives you the completed look of the graph for this equation.
It should look like this:

Multiplicity is how many times the root (or zero) is repeated
example, in
the root b has a multiplicity of n and the root d has a multiplicity of m
first we need to get the roots into
for (3x+5), we need to force factor out the 3 to get
factor the other one
but it is
which is equivilent to 
which simplifies to 
so we get
so the roots are -5/3 multiplicity 1 and 3 multiplicity 4
3 has a multilicity of 4
