Answer:

Step-by-step explanation:
(f g)(x) is equal to f(x) times g(x). So you just need to multiply both of the equations together. Use the foil method to multiply (x+2)(x-4)

I have attached an image to better explain the foil method
Answer: (x, y) transforms into (-x, y)
Step-by-step explanation:
When we do a reflection over a given axis, the distance between the initial point to the axis must be the same as the distance of the reflected point to the axis.
So if we do a reflection over the y-axis, then the value of y must be fixed.
So if we start with the point (x, y), the only other point that is at the same distance from the y-axis is the point (-x, y)
So the rule is, the y value remains equal and the x changes of sign.
Answer:
(a+b)2 = a² + b² + 2×a×b

Answer:
8 gallons
Step-by-step explanation:
#1: Set up a ratio from the recipe: gallons of punch to the number of people.
2 gallons 15 people
#2: Set up a ratio of gallons to the people coming to the party.
(Place the gallons on top) x gallons 60 people
#3: Set up a proportion 2 gallons x gallons
15 people = 60 people
* Like units should be across from each other
4) Solve using the "lonely mate" formula
2 gallons x gallons
15 people = 60 people
2 x 60 = 120
120/15 = 8
This means she should make 8 gallons.
