Answer:
Step-by-step explanation:
If J can paint a room in 3 hours, in 1 hour she gets 
of the job done.
If A can paint a room in 4 hours, in 1 hour she gets 
of the job done. We need to find out how long it takes them if they paint together. The equation for this is:
where x is the number of hours it takes them to get the job done together. Multiply everything through by 12x to get
4x + 3x = 12 so
7x = 12 and
x = 1.7 hours to get the room painted together.
<u>ANSWER:</u>
<span>The initial value of the truck is $22,200
</span>
<u>EXPLANATION:</u>
For the given function
<span>
f(t) = 22,200(0.92)^t
We know that at t = 0, we have
</span> f(0) = 22,200(0.92)^0 = 22,200
<span>
which is the value of the truck initially. So, the correct answer is
</span>The initial value of the truck is $22,200

Answer:
This equation is false
Step-by-step explanation:
Well,
-11b + 7 = 4 - 11b + 7 = 40
combine like terms
-11b + 7 = -11b + 3 = 40
Communicative property
-3 to both sides
-11b + 4 = -11b = 40
-4 to both sides
-11b = -11b = 36
+11b to both sides
0 = 36
0 is not equal to 36 meaning that this equation is false.
<em>Thus,</em>
<em>the equation given is false.</em>
