Answer:
p>-3 open circle going to the right
closed circle going to the left
n<5 open circle going to the left
closed circle going to the right
1>x open circle going to the left
-1=d just a closed circle
Step-by-step explanation:
Before I answer these here are some good notes
If the inequality sign is < or > then the circle is going to be open
If the inequality sign is then the circle is going to be closed
If the inequality sign is facing the variable (ex: x>3) then the line is going to be going to the right
If the inequality sign is facing the constant (ex: x<3) then the line is going to be going to the left
p>-3 open circle going to the right
closed circle going to the left
n<5 open circle going to the left
closed circle going to the right
1>x open circle going to the left
-1=d just a closed circle
Graphs of y = x+- 1 and of y = x - 1 are shown in the figure below.
The intersection of the two graphs is the solution for the two equations.
Answer:
There is no solution.
Explanation:
It is clear that the two lines are parallel and will never intersect.
Note that the equation for a straight line is of the form
y = mx + b
where
m = slope,
b = y-intercept.
y = x + 1 has slope of m=1.
y = x - 1 has slope of m=1.
The two slopes are equal.
Because parallel lines do not intercept, there is no solution.
