So Maurice would have 2N nickels  

Total number of coins is N + 2N + 9 = 3N + 9  

Each nickel is 5 pennies  

3N of nickels = 15N pennies  

-----------  

Their worth is 84 cents  

15N + 9 = 84  

15N = 75  

N = 75/15 = 5  

N = 5  


This means Nina has 5 nickels.

H(x) = 1/3x - 1 if h (15)
dalvyx [7]

Answer:

(

h

∘

f

∘

g

)

(

x

)

is known as a composite function. Here's how composite functions work:

let's say that  

x

=

1

. Your function  

g

(

x

)

=

1

3

(

x

)

now produces a  

y

output of  

1

3

, since  

g

(

1

)

=

1

3

(

1

)

. Within a composite function, the y-value of one function becomes the x-value of the next, like so:

g

(

1

)

=

1

3

⇒

f

(

1

3

)

=

17

3

⇒

h

(

17

3

)

=

17

Therefore,

(

h

∘

f

∘

g

)

(

1

)

=

17

Based on this, to find the function for  

(

h

∘

f

∘

g

)

(

x

)

(combined from right to left, by the way), simply replace  

x

in  

f

(

x

)

with the function  

g

(

x

)

, and replace  

x

in  

h

(

x

)

with the function of  

(

f

∘

g

)

(

x

)

, to get  

(

h

∘

f

∘

g

)

(

x

)

.

This, simplified, is equal to  

2

x

+

15

, and therefore  

(

h

∘

f

∘

g

)

(

1

)

=

2

(

1

)

+

15

=

17

Hope that helps!

otez555 [7]

Answer:

The answer is 2x + y - 3z

Step-by-step explanation:

∵ log_{2}P=x

∵ log_{2}Q=y

∵ log_{2}R=z

∵ log_{2}\frac{P^{2}Q}{R^{3}} =

  log_{2}P^{2}+log_{2}Q-log_{2}R^{3} =

  2log_{2}P+log_{2}Q-3log_{2}R

∴ 2x + y - 3z
