x+9>2

how do I solve and graph this?

The graphing part would be hard to explain. The equation, you solve the same as if the greater than sign (>) was an equal sign. (But don't change it to an equal sign)

a+b>c

To solve for a:

a>b-c

I'm stupid sometimes. That last line should be:

a>c-b

Matt

so would the answer be 7 and a dotted line?

I'm sorry i met -7

x > -7
Good job
And yes to the dotted line. Just don't forget to shade it in too.

To solve and graph the inequality x + 9 > 2:

Step 1: Start by isolating the variable 'x' on one side of the inequality. To do this, subtract 9 from both sides:
x + 9 - 9 > 2 - 9
x > -7

Step 2: Now you have the solution x > -7, which means any value of 'x' greater than -7 satisfies the inequality.

Step 3: To graph this inequality on a number line, you would first locate -7 on the number line and mark it with an open circle (since the inequality is strictly greater than). Then shade to the right of -7 since any value greater than -7 is a solution to the inequality.

Note: Make sure to use a dotted line for the arrow to indicate that the circle is open.
