f(-2) = 4

Step-by-step explanation:

The function has three definitions depending on the value of x.

You are looking for the value of the function at x = -2.

-2 is in the interval x <= -1, which is the first line of the definition of the function.

We use the first line of the definition of the function.

f(x) = -2x for x <= -1

f(-2) = -2(-2) = 4

f(-2) = 4

step-by-step explanation:

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:
