Pi r² is circle's area expression.
So the r is radius,.
Answer:
Step-by-step explanation:
The expression representing the amount of money that the photographer would make from selling 10 copies is given as
10(0.75p - 0.5)
where p represents the price determined for each copy. Assuming the price charged per copy is $5, then the amount made from 10 copies is
10(0.75 × 5 - 0.5) = $32.5
It could have been
10(5 - 0.5) = $45
The price is being reduced by 25%(100 - 75)
Therefore, the option that most likely describes the agreement between the online service company and the photographer is
A. The company keeps 25% of the amount paid for each copy and charges the photographer $0.50 for every copy purchased.

Answer:
slope = k/2
Step-by-step explanation:
The slope formula is useful for finding slope.
m = (y2 -y1)/(x2 -x1)
m = (5k -7k)/(-3 -1)
m = -2k/-4
m = k/2
The slope is k/2.
Okay, so this is basically telling you that there is no solution. You don't have to worry about there being one. You just have to justify (or explain) why there isn't one.
Basically, neither y or x is equal to anything. You couldn't make x equal to a value in y because x and y are both together in the equation and equal to numbers.
We can always move a factor to the other side. So,
x-2y= -8
Add 2y to the other side.
x= -8+2y
Now, plug in -8+2y as x.
3(-8+2y)- 6y=-12
-24+6y-6y= -12
The 6y's cancel out. So, we can't figure out what y is.
-24=-12 <- no y.
These two lines are parallel. They have direct proportion in each other. That is why there is no solution because the lines never cross. Parallel lines do not cross.
I hope this helps!
