Answer:
It will take 100 songs for the monthly price of Napster to cost the same as iTunes.
Step-by-step explanation:
Let's create two equations to represent iTunes (T(d)) and Napster (N(d)):
T(d)=0.99d
N(d)=0.89d+10
In order for us to find when the two prices will be the same, let's set the equations equal to each other and solve for x:
0.99d=0.89d+10
0.1d=10
d=100
Answer:
-2.35
Step-by-step explanation:
Divide -4.7/2 = -2.35
The answer to <span>H+12.5=-12.5</span> is H=-25
The first thing you do is substitute 9 for y in the function, which is,
9 - 4 = 5/6 (x - 2)
Then, you subtract on the left side
5 = 5/6 (x - 2)
Then, you multiply by 6 on both sides
30 = 5 (x - 2)
Then, divide both sides by 5
6 = x - 2
Then, at 2 on both sides to isolate x
& your final answer is
x = 8 (this would be the missing value)
