5 star coffee : f(x) = 8x + 40....or y = 8x + 40
custom coffee : f(x) = 12.5x + 25 or y = 12.5x + 25
the monthly fee of custom coffee, which has a monthly fee (slope) of 12.5, will have a steeper slope then the monthly fee (slope) of 5 star coffee, which has a slope of 8.
8x + 40 = 12.5x + 25
40 - 25 = 12.5x - 8x
15 = 4.5x
15/4.5 = x
3 1/3 = x.......so they would cost the same at 3 1/3 months
Therefore, custom coffee would be a better deal if u were a member for less then 3 1/3 months......and 5 star coffee would be a better deal if u were there for more then 3 1/3 months
Answer:
the answer would be A.
Step-by-step explanation:
it would be that answer because to or more simple things are more likely to happen. like tossing 5 coins and getting 4 heads . SIMPLE.
Answer:
The simplest form of the given expression is 7x³ + 5x² + x + 2
Step-by-step explanation:
(4x³ + 6x - 7) + (3x³ - 5x² - 5x + 9)
Group like terms together.
(4x³ + 3x³) + 5x² + (6x - 5x) + (-7 + 9)
Combine like terms.
7x³ + 5x² + x + 2
So, this will be your simplest form of the given equation.
Answer:
Sara could list the factors of 18 and 30 then find the greatest value the lists have in common. The length of the longest equal-sized pieces she can cut from both boards, with no wood left over, is 4.8 inches. She will be able to cut 3.75 pieces from the 18-inch board and 2.08 pieces from the 30 inch board. She would have enough wood to cut 10-equal pieces for he club project.
