One song download costs $2 and one movie download costs $11.
Step-by-step explanation:
Let,
Price of one song download = x
Price of one movie download = y
According to given statement;
8x+9y=115 Eqn 1
15x+9y=129 Eqn 2
Subtracting Eqn 1 from Eqn 2
Dividing both sides by 7
Putting x=2 in Eqn 1
Dividing both sides by 9
One song download costs $2 and one movie download costs $11.

Area of one face = 3 * 7 = 21 sq inches
</span>Area of 2nd face = 4 * 7 = 28 <span>sq inches

Two forces act on the fish, and these are:
1) Its weight mg, downwards and
2) pressure in the string, T, upwards which is 22 N when the string breaks.
In the result of these two forces, the fish had an acceleration of 2.5 m/s^2 in
the upward way.
So, T - mg = m*2.5
=> m = T / (2.5 + g)
=> m > 22 / (2.5 + 9.8) ( when the string snaps )
=> m > 1.79 kg.
As a result, the mass of the fish is more than 1.79 kg as the line has been broken.
Let
x-------> the number of hours
y------> the temperature in degrees Fahrenheit
we know that
For 
For 
The domain of the function is the interval----------> ![[0,30]](https://tex.z-dn.net/?f=%5B0%2C30%5D)
The range of the function is the interval----------> ![[-10,30]](https://tex.z-dn.net/?f=%5B-10%2C30%5D)
therefore
<u>the answer is</u>
The domain is all real numbers 0 through 30
He is, since each number is 4 more in value than the previous number
