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.
