Note how all four answer choices begin with "x=-2(." This tells us that we have the graph of a horizontal parabola that opens to the left, because of the "-" symbol.
Given that the vertex is located at (-1,-3), we know that the (y-c) term must be (y-[-3]), or (y+3). Thus,we can immediately eliminate answer choices b and d
The only answer choice that fits this situation is (a): x = -2(y+3) - 1.
Answer:
You could order 16 different kinds of pizza.
Step-by-step explanation:
You have those following toppings:
-Pepperoni
-Sausage
-Mushrooms
-Anchovies
The order is not important. For example, if you choose Sausage and Mushrooms toppings, it is the same as Mushrooms and Sausage. So we have a combination problem.
Combination formula:
A formula for the number of possible combinations of r objects from a set of n objects is:
How many different kinds of pizza could you order?
The total T is given by
is the number of pizzas in which there are no toppings. So
is the number of pizzas in which there are one topping is a combination of 1 topping from a set of 4 toppings. So:
is the number of pizzas in which there are two toppings is a combination of 2 toppings from a set of 4 toppings. So:
is the number of pizzas in which there are three toppings is a combination of 3 toppings from a set of 4 toppings. So:
is the number of pizzas in which there are four toppings. So
Replacing it in T
You could order 16 different kinds of pizza.
There is no equ, we cant answer.
