If f(x)=3x^2+1 and g(x)=1-x what js the value of (f-g)(2)?

14.

Step-by-step explanation:

Simplify:

f(x)-g(x)

3x^2+1 - (1-x)

3x^2+ x

Solve:

(f-g)(2)

3(2)^2 + 2= 3*4+2

= 14

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:

1) is right
