if f(x)= 3x-2 and g(x)= x^2-5, what is g(f(2))

a. 11

b. -5

c. -4

d. 3

Step-by-step explanation:

f(x)=3x-2

f(2)=3(2)-2

f(2)=6-2

f(2)=4

When you solve f(x) for x=2, you get f(2)=4. This means that g(f(2)) is equal to g(4). Now, you can solve g(x) for x=4.

g(4)=4^2-5

g(4)=16-5

g(4)=11

g(f(2))=11

So the answer is A, 11.

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:
