Answer:
Step-by-step explanation:
Total amount of Money saved by Manny is $150. He wants to buy a digital player with it.
The digital music player costs $89, and each song costs $0.99. Let x represent the number of songs that he can afford. This means that the cost of x songs would be
89 + 0.99x
If Manny spends no more than $150, before tax, the number of songs that he can buy will be
89 + 0.99x = 150
0.99x = 150 - 89 = 61
x = 61/0.99 = 61.6
He can buy 61 songs

Answer:
either d or a
Step-by-step explanation:
The general equation of a circle is
where a and b are the x and y components of the center respectively.
In order to get into this format, we have to use a method that I'm drawing a blank on the same, my apologies about that.
Anyway, what you want is to first isolate the variable on side so now you have:
(you'll see why I rearranged this soon)
Now you have to make it into an equation that can be simplified into the format stated earlier.
So, You have to take the x & y terms (-4x & -8y in this case) divide them each by two, and then square them.
The result of this step is the equation:
Notice the new components that have been added (4 & 16) and how the have been
added to both sides. That is an important step.
Now we simplify and get:
So the coordinate of the center is: (2,4) and the radius is 5
