Let x represent the number of half-gallons purchased by the store. Then x-13 is the number sold, and 2.80x is the store's cost. The revenue is 4.06(x-13) and the difference between that and cost is the profit.
... 4.06(x -13) -2.80x = 63.14
... 1.26x - 52.78 = 63.14 . . . . eliminate parentheses, collect terms
... 1.26x = 115.92 . . . . . . . . . . add 52.78
... x = 115.92/1.26 = 92 . . . . . divide by the coefficient of x
The store purchased 92 half-gallons of milk.

Answer:
we get rectangular coordinates,
x= 
y = 
Step-by-step explanation:
We have given,
Polar coordinates ,P = (r , θ) = (3 , 
)
We nee to find rectangular coordinates:
Since , x =rcosθ and y = rsinθ
i.e x = 3cos(frac{-pi}{3}[/tex]) = 3×
=
And y = 3sin(frac{-pi}{3}[/tex]) = 3×
=
Hence we get rectangular coordinates,
x=
y =
Answer:
for A plug in those numbers on the right and on the left start with 1 and move up(for example 1,2,3,4,5...)
For b the answer is 2.5x²−4.5x+1.
