Your parents give you 1 cent to clean up your kitchen on aug. 15. they will double the amount of money they give you on the following day(aug.16, 2 cents, aug. 17, 4 they continue to double the amount and give you money everyday. how much money will you make from aug 15 to aug 31? is it a good deal?

Step-by-step explanation:

Aug

15 = 1     26 = 23.04    Total $737.28 that's a great deal

16 = 2    27 = 46.08

17 = 4    28 =  92.16

18 = 8    29 =  184.32

19 = 16   30 = 368.64

20 = 36   31 = 737.28

21  = 72  

22 = 1.44

23 = 2.88

24 = 5.76

25 = 11.52

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
