Answer:
27. My fiend solved the inequality correctly but graphed it incorrectly. The statement "x > 5" is correct but but since the symbol is "greater than" it should have been graphed with an open circle to the right rather than a closed circle to the right.
28. My friend is incorrect for both solving the inequality and graphing. The correct answer for solving the inequality would be "5 ≥ x ". And for graphing the correct answer would be closed circle to the right since the symbol is greater than.
Step-by-step explanation:
27. Solving the inequality
x - 7 > -2
+ 7 + 7
------- ------
0 5
answer: x > 5
Graphing the inequality
Since the symbol is greater than, it would be a open circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 28 the symbol is just greater than, not greater than or equal to.
28. Solving the inequality
8 ≥ x + 3
-3 - 3
-------- --------
5 0
answer: 5 ≥ x
Graphing the inequality
Since the symbol is greater than than or equal to, it would be a closed circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 27 the symbol is just greater than or equal to, not just greater than.
This might not be the right way to do it or the right answer for that matter, I am very new to solving and graphing inequalities so I just decided to give this one a shot.
Hope this helps ; )
