You would just break each one into 2 separate equations and solve for x/r. Then write the answer in between the two inequality signs- so the answers for 9 and 11 would look like this, just fill in the blanks with the answer you got: 3<span>≤____<5, 2>___>-2.
</span>
0<span>≤x-2<3
1</span><span>≤x-2 and x-2<3
</span><span>-1>2r-5>-9
-1>2r-5 and 2r-5>-9
this one just solve each one for z.
2z-1</span>≤5 or 3z-5>10
<span>z≤3 or x>5</span>

Answer:
The decrease is 21%
Step-by-step explanation:
So lets say the Original area is Pi X (Radius^2)
Lets call Radius as R
For the new radius, it would be: R + 0.1R which is 1.1R
The new area is: Pi X 1.1R^2, which going further is 1.21 after squaring 1.1.
The Original area is: Pi X Radius^2
To find the percent decrease, subtract the new area by the original, cross out Pi X Radius squared and you are only left with 21%
I am in middle school so I don't know if it is going to be incorrect, but I ask you to give it a try and tell me if it was right or not. I have barely done this topic but recently I had a bonus homework question on a question almost exactly like this and this is the way I did it and I was correct. Thanks! Hope it helped! :)
Answer:
The inequality shown is p>-3
Explanation:
An open hole on the number line means that the inequality will be greater or less than a number. So far we have p <or> some number.
Since the line goes to the left then we know that p is greater than some number. Now we have, p> some number.
The inequality starts at -3 so we know that the equation must be p>-3.
