I say D because sum is the total when you add and when it says less you go backwards ex.2 less than 3 this is how you write it 3-2
Answer:
x = 2.125 + 0.375y
Step-by-step explanation:
Simplifying
8x + -3y = 17
Solving
8x + -3y = 17
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '3y' to each side of the equation.
8x + -3y + 3y = 17 + 3y
Combine like terms: -3y + 3y = 0
8x + 0 = 17 + 3y
8x = 17 + 3y
Divide each side by '8'.
x = 2.125 + 0.375y
Simplifying
x = 2.125 + 0.375y
Answer:
<h2>440 square units</h2>
Step-by-step explanation:
We can find half of a side of the pentagon with the expression

Because, as a regular polygon, all its sectors have the same central angle, and the apothem divides equally each sector in two equal parts.

Therefore, half of a side is 8 units long, which means each side measures 16 units.
Now, the area of a penthagon is defined by

Where
is the perimeter and
is the apothem. Where the perimeter is the sum of all sides, which is 80 units.

Therefore, the right answer is the second choice.
Answer:
Exponential function
Step-by-step explanation:
It is better if the situation on ground is represented by an exponential equation.
This is because, since we have the number of teams reducing by exactly half at every playoff round, this means that we have a base of 2 which can be raised to a negative power since we are talking about a decrease.
We can then place the number of rounds as an adjoining power to what the two is raised and this easily will get us the number of teams which is eventually decreased at every point of the playoffs
