When graphing inequalities on the number line, which of the following statements are true? Select all that apply.
Softa [21]

Answer:

The correct options are;

1) "Greater/Less than or equal to" means the circle on the number will be SOLID

2)"Greater/Less than" means the circle on the number will be open

3) If It is "greater than", the line will be colored to the RIGHT of the number & if it is "less than", the line will be colored to the LEFT of the number line

Step-by-step explanation:

When a linear inequality is graphed on a number line, and the value of the inequality is "less than" or "greater than" the limit displayed on the number line, the limit of the inequality is indicated by an open

When the the limiting value of the inequality is specified as "less than or equal to" or "greater than or equal to" the value displayed on the number line as a SOLID circle.

The region where the inequality is valued on the number line is the colored region.

✺ ・*:.。. .。.:*・゜゚・*☆ Hey There ☆ ・*:.。. .。.:*・゜゚・*☆ ✺

★━━━★━━━★━━━★━━━★━━━★━━━★━━━★━━━★

The answer to this is:

Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10 ÷ 190 = 5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175 = 14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.
