Use the table below to figure out which x-values are solutions to the equation and which ones are solutions to the inequality. Show your work in the rows of the table.
Question 2
2.
From your table above, how many solutions are there to the equation 2x+3=5? Explain.
Question 3
3.
Which numbers in the table are solutions to the inequality 2x + 3 > 5? Are these the only solutions to the inequality? Explain.
Question 4
4.
Would 1 be a solution to the inequality 2x + 3 ≥ 5? Explain.
Here are the number line graphs of two different inequalities. Use these to answer #5-7.
Question 5
5.
Use the graphic organizer to compare and contrast the two inequalities and graphs that are shown above.
Question 6
6.
Look at the graphs above. Why is one of the graphs showing a solid ray going to the left and the other graph showing a solid ray going to the right?
Question 7
7.
Look at the graphs above. Why does one graph have an open circle and the other graph a filled-in circle?
