When two variables are related in such a way that the ratio of their values always remains the same, the two variables are said to be in direct variation.
In simpler terms, that means if A is always twice as much as B, then they directly vary. If a gallon of milk costs $3, and I buy 1 gallon, the total cost is $3. If I buy 10 gallons, the price is $30. In this example the total cost of milk and the number of gallons purchased are subject to direct variation -- the ratio of the cost to the number of gallons is always 3.
To be more "geometrical" about it, if y varies directly as x, then the graph of all points that describe this relationship is a line going through the origin (0, 0) whose slope is called the constant of variation. That's because each of the variables is a constant multiple of the other.Hope I helped
You can take x = a, 2y = b and then can apply the binomial theorem.
The expansion of given expression is given by:
Option D: is
<h3>What is binomial theorem?</h3>
It provides algebraic expansion of exponentiated(integer) binomial.
According to binomial theorem,
<h3>How to use binomial theorem for given expression?</h3>
Taking a = x, and b =2y, we have n = 7, thus:
Thus, Option D: is correct.

Answer:
Hi there!
Your answers are:
As the pizza size increases, the topping price increases and the base price increases
The small pizza:
Base price: $9.49
Price per topping: $1.39
The medium pizza:
Base price: $11.49
Price per topping: $1.59
The large pizza:
Base price: $13.49
Price per topping: $1.79
The XL pizza:
Base price: $15.49
Price per topping: $1.99
Step-by-step explanation:
small:
15.05- 12.27 = 2.78 for TWO toppings
2.78/ 2 = 1.39$ per 1 topping
12.27 - 2.78 = 9.49$ for a plain pizza
medium:
17.85-14.67 = $3.18 for TWO toppings
3.18/2 = $1.59 per 1 topping
14.67- 3.18= $11.49 for plain pizza
large:
20.65-17.07= $3.58 for TWO toppings
3.58/ 2 = $1.79 per 1 topping
17.07- 3.58= $13.49 for plain pizza
xl:
23.45- 19.47= $3.98 for TWO toppings
3.98/2 = $1.99 per 1 topping
19.47- 3.98 = $15.49
I hope this makes sense! Let me know if you need clarification!
Answer:
Since the 2 on the spinner takes up one half, the answer would be B.
