4. Use the function f(x) = 2x + 5. When asked to find the value of x for which f(x) =17, Hudson answered 39. What mistake did Hudson make? What is the correct answer?

The correct answer is 6. Hudson evaluated the function at x =17, instead of finding the the value of x.

Step-by-step explanation:

2( 1/2)+5

1+5= 6

answer: c i think

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:
