The vertex form of the equation of a parabola is y=4(x-2) squared minus one what is the standard form of the equation

y = 4x² - 16x + 16

Step-by-step explanation:

Standard form is y = ax² + bx + c

To convert from vertex form to standard form multiply out the equation

1. Solve (x-2)² using F.O.I.L.

(x - 2) · (x - 2) = x² - 4x + 4

y = 4(x² - 4x + 4)

2. Distribute the 4

y = 4x² - 16x + 16

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:

he sells x mount because thats eqivilqant to the maz and then divided into quarters
