Question 958068: Your or compound inequality
1 x ≥ -3 or 5x 1 > 19
Solve the compound inequalities Be careful of how a negative x-term is handled in the solving process. Show all math work arriving at the solutions.
Show the solution sets written algebraically and as a union or intersection of intervals. Describe in words what the solution sets mean, and then display a simple line graph for each solution set.
Answer by stanbon(75887)   (Show Source):
You can put this solution on YOUR website! 1 x ≥ -3 or 5x 1 > 19
-x>=-4 or 5x > 20
x <= 4 or x > 4
Note: This pair of conditions covers the entire number line.
------
Ans: (-oo<4]U(4,+oo)
---------------------------
Draw a number line.
Plot x = 4 as a closed circle on the line.
Draw an arrow from 4 to the left.
Draw a circle from 4 to the right.
