Answer:
x equals plus or minus square root of 5 minus 1
Step-by-step explanation:
we have

Divide by 2 the coefficient of the x-term

squared the number

Adds both sides


Rewrite as perfect squares

take the square root both sides


therefore
x equals plus or minus square root of 5 minus 1
Answer:
3rd degree
Step-by-step explanation:
The highest exponent is a 3, meaning this is a 3rd degree polynomial.
If each player will receive 7/8 of a cup, and there are a total of 20 cups of lemonade, then the number of servings that can be made is equal to:
20 cups divided by (7/8 cup per player)
20 / (7/8) = 20 * (8/7) = 160/7 = 22 and 6/7 (round down since we're looking for complete servings)
This means that 22 complete servings can be made.
Answer:
(2,4).
Step-by-step explanation:
Graph of y = f(-x).
The values of x in f(-x) assume the values of -x in f(x).
For example, f(-2) in f(x) is f(2) in f(-x), and f(2) in f(x) is f(-2) in f(-x).
b) Write down the coordinates of the maximum point of the graph of y = f(-x).
In f(x), we have that x = -2. So in f(-x), it will be x = 2. y remains unchanged. So
(2,4).
