Which graph shows the solution set for 2 x plus 3 is greater than negative 9 ?
Answer
A
Image with description A number line ranges from negative 8 to 2 by ones. An open circle is on negative 6. A ray is drawn from that circle pointing to the right.
B
Image with description A number line ranges from negative 8 to 2 by ones. An open circle is on negative 6. A ray is drawn from that circle pointing to the left.
C
Image with description A number line ranges from negative 8 to 2 by ones. An open circle is on negative 3. A ray is drawn from that circle pointing to the left.
D
Image with description A number line ranges from negative 8 to 2 by ones. An open circle is on negative 3. A ray is drawn from that circle pointing to the right.
Explanation
Subtract 3 from both sides: 2x > -12. Divide by 2 to get x > -6, so the graph has an open circle at -6 and a ray pointing to the right. That is choice A.
