Question

4: Write the solution to the compound inequality in compact form, write the solution in interval notation, and describe the graph.
Write in compact form:
-5 < 3x + 4 < 19

3 < x < 23/3
-3 < x < 23/3
3 < x < 5
-3 < x < 5


5: Write the above solution in interval notation:
(3, 5)
(-∞, 5)
(-3, 5)
(-∞, ∞)


6: Describe the above graph.
the entire graph is shaded
open circle on 5, and shaded to the left
open circle on -3, and shaded to the right
open circle on -3, open circle on 5, and shaded in between


7: Write the solution to the compound inequality in compact form, write the solution in interval notation, and describe the graph.
Write the solution in compact form:
1 < y + 2 < 12

-2 < y < 10
-1 < y < 10
2 < y < 12
2 < y < 12


8: Write the above solution in interval notation:
(-1, 10)
(-1, ∞)
(-∞, 10)
(-∞, ∞)


9: Describe the above graph.
the entire graph is shaded
open circle on -1, and shaded to the right
open circle on -1, open circle on 10, and shaded in between
open circle on 10, and shaded to the left

Answer 1

- 5 < 3x + 4 < 19

- 5 - 4 < 3x + 4 - 4 < 19 - 4

- 9 < 3x < 15

- 9/3 < 3x/3 < 15/3

- 3 < x < 5
