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:
1)Solving the expression we get
2) solving the equation we get
Step-by-step explanation:
We need to solve the expressions:
1)
Solving
First solving the brackets
Simplifying
Adding 4x on both sides
Switching the sides
Divide both sides by 3
So, Solving the expression we get
2)
Solving:
Adding 6.1 on both sides
Adding 2.4x on both sides
Divide both sides by 6
So, solving the equation we get
Builder can build 7 one bedroom houses and 5 two bedroom houses.
What is consistent Equation?
A linear or nonlinear system of equations is called consistent if there is at least one set of values for the unknowns that satisfies each equation in the system—that is, when substituted into each of the equations, they make each equation hold true as an identity.
Let x represents the number of one-bedroom houses and y represents the number of two bedroom houses.
According to Question,
Total number of houses is 12 i.e. x + y = 12..........(i)
Total we have 88 windows in which 6 windows can be use in one bedroom house and 9 windows can be used in two bedroom house so,
6x + 9y = 88 ..................(ii)
From Equation (i) and (ii), we get
x = 7 and y = 5
Thus, Builder can build 7 one bedroom houses and 5 two bedroom houses.

Answer:
x = 5
Step-by-step explanation:
I just solved the equation!
5 - 4(2-x) = 17
-4(2-x) = 12 (subtract by 5 on both sides)
2 - x = -3 (divide by 4 on both sides)
-x = -5 (subtract by 2 on both sides)
x = 5 (divide by -1 on both sides (two negatives cancel out!))
