f(g(x)) is a composite function:

f(g(x))=f(\sqrt{x+5})=2\sqrt{x+5}-1

Plug in <em>x</em> = 4:

f(g(4)) = 2\sqrt{4+5}-1=2\sqrt9-1=2\cdot3-1=\boxed{5}

so the answer is C.

22 is 44percent of what number
Alborosie
First, you would need to create an equation for this problem.
\frac{22}{x} = \frac{44}{100}

Next, you would need to cross multiply. 
44x = 2,200

Now, all you would have to do is isolate the x. To do this, you would divide both sides by 44. 
x = 50

22 is 44 percent of 50. 

I hope this helps!

At the movies, Hunter bought 3 popcorn and 5 drinks. Each popcorn
anastassius [24]

Answer:

P= $2.75

Step-by-step explanation:

So first we need to create our system of equations

since each popcorn is 0.40 less than each drink we can make the equation:

D - 0.40 = P we can rewrite that as P + 0.40 = D so that we have D by its self.

Next, we create the overall equation:

$24.00 = 3P + 5D

Now plug in D from the first equation into the second equation:

$24.00 = 3P + 5( P + 0.40)

Distribute the five and solve for P:

$24.00 = 3P + 5P + 2

$22.00 = 8P

P = $2.75

Now add 0.40 which would be $3.15 and plug it into the first equation just to make sure that the answer is correct.
