Answer:
10/14, 15/21, and 20,28
Step-by-step explanation:
You just need to multiply a number on the numerator and the denominator. Remember, whatever you do to the numerator you have to do on your denominator.
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.
Al factorizar la expresión dada obtenemos que es igual a x²*(5 - x)*(5 + 5)
Por propiedad de los números reales: tenemos que para a y b dos números reales, se cumple que:
(a² - b²) = (a + b)*(a - b)
Por lo tanto como tenemos: - x⁴ + 25x², ordenamos:
- x⁴ + 25x² = (25*x² - x⁴ = ((5x)² - (x²)²)
Usando la propiedad dada inicialmente: obtenemos que:
((5x)² - (x²)²) = (5x - x²)*(5x + x²)
Sacamos de cada término un factor común "x":
x*(5 - x)*x*(5 + x) = x²*(5 - x)*(5 + 5)

Answer:
q(5,-8) s(-1,3)
Step-by-step explanation:
you just have to add a negative to the y-axis point, if you reflect across the x-axis
Given:
You order 1.5 pounds of turkey at the deli. You will accept the turkey if its weight is between 1.54 and 1.46 pounds.
To find:
The absolute value inequality that can be used to describe the tolerance of the weight of the turkey
Solution:
Let x be the actual weight of the turkey.
It will accepted, if its weight is between 1.54 and 1.46 pounds.
Subtract 1.5 from each side.
Therefore, the required absolute inequality is .
