The functions fand g are defined as follows. 3 f (x) = 3x - 5 g(x) = – 4x-1 Find f(-2) and g(?).

Simplify your answers as much as possible.

f(-2)= []
g(2)= []

see below

Step-by-step explanation:

f (x) = 3x - 5

g(x) = – 4x-1

f(-2)=

Let x =-2

f(-2) = 3*-2 -5 = -6-5 = -11

g(2)=

Let x=2

g(2) = -4(2) -1 = -8-1 = -9

Step-by-step explanation:

The input value or x value for f(-2) is -2.

The input value or x value for g(2) is 2.

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:
