F(x) = 6x + 2

find f(4)

f(4) = 26

Step-by-step explanation:

To solve this equation, you need to replace all x's with 4s. So you would make

f(4) = 6(4) + 2 (basically subsitiute x for 4)

Then, you just need to solve the equation! 6 x 4 is 24, and 24 plus two equals 26! Hope this makes sense!

is it 35

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:
