We have that
2r−9≤−6------> 2r ≤ -6+9-------> 2r ≤ 3-----> r ≤ 1.5
the solution is the interval (-∞, 1.5]
using a graph tool
see the attached figure
Find the volume of the first figure, then find the volume of the second figure, then add them together.
V=lwh
V(1)=(15)(12)(6)
= 1,080in^3
V(2)=(12)(6)(6)
= 432in^3
--------------------------------------------
1,080+432= 1,512 in^3
--------------------------------------------
Your answer should be 1,512

In reality, it is already a function, because for every x only one corresponding value of y.
We do not see any repeating values of x, so this set is already function. We do not have to remove anything.</span>
<u>To factorize something</u>:
⇒ need to simplify the equation to its most basic form
<u>Let's solve</u>:
Thus the factorized form is ⇒ 
<u>Answer: 2x(x+3)</u>

Hope that helps!
