Which function has a minimum and is transformed to the right and down from the parent function, f(x) = x??
g(x) = -9(x + 1)2 - 7
g(x) = 4(x – 3)2 + 1
g(x) = -3(x – 4)2-6
g(x) = 8(x – 3)2-5

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

current in the circuit at time t is /, then the power delivered to the resistor is
