F (×)=-4×+2 g (×)=-2×^3-5 find f (5) and g (-3) Show work please

f(x) = 22

g(x) = 19

Step-by-step explanation:

in f(x) replace all x with 5

f(5) = 4* 5 +2

     = 20+2 = 22

in g(x) replace all x with -2

g(-3) = -3 * -5 = 24 -5

  = 19

answer: 7270

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:
