In the second week of the sale, the prices are reduced buy 25% of the previous week's price. In the third week of the sale, ther prices are again reduced by 25% of the previous week's price. In the fourth wee of the sale, the prices are reduced by 25% of teh previous week's price. Julie thinks this will bmean that the price wil be reduced to $0 after the four reductions because 4 x 25% = 100%.
Explain why Julie is wrong.

g(x) is the negative form of f(x)? because whenever its the negative form it reflects its self over the x axis. idk if this is right though.

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

just get this app called photo math it should be able to do those

the answer i believe is 27 units.
