Average rate of change is just the slope betwen the points
that is just the slope between (-3,-3) and (-4,-1)

slpe between (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)

so slope between (-3,-3) and (-4,-1) is (-1-(-3))/(-4-(-3))=(-1+3)/(-4+3)=2/-1=-2

the average rate of change is -2

Encuentre el resultado de la diferencia de las fracciones: 9 /12 - 2/3=

Veronika [31]

Responder:

1/12

Explicación paso a paso:

Entonces multiplicamos 9 por 3 y obtenemos 27.

Luego multiplicamos 2 por 12 y obtenemos 24.

A continuación, le damos a ambos términos nuevos denominadores: 12 × 3 = 36.

Así que ahora nuestras fracciones se ven así:

Paso 2

Dado que nuestros denominadores coinciden, podemos restar los numeradores.

27 - 24 = 3

Entonces la respuesta es:

Paso 3

Por último, necesitamos simplificar la fracción, si es posible. ¿Se puede reducir a una fracción más simple?

Para averiguarlo, intentamos dividirlo por 2 ...

¡No! Así que ahora probamos con el siguiente número primo mayor, 3 ...

¿Son tanto el numerador como el denominador divisibles por 3? ¡Sí! Entonces lo reducimos:

÷ 3 =

Natalie baked 20 cupcakes for a fundraising event at school. On the way to the event she dropped 35% of the cupcakes on the floo

FinnZ [79.3K]

Answer:

The total number of cupcakes that Natalie dropped is 7.

Step-by-step explanation:

This question can be solved using a rule of three.

The amount of cupcakes that she has, which is 20, is 100% = 1. How many cupcakes is 35% = 0.35?

20 cupcakes - 1

x cupcakes - 0.35

x = 20*0.35 = 7

The total number of cupcakes that Natalie dropped is 7.

A set of weights includes a 10 lb barbell and 8 pairs of weight plates. Each pairof plates weighs 20lbs. If x pairs of plates ar

Leni [432]

It is given that the weight of the barbel is given by:

$f(x)=20x+10$

It says that there are eight pair of weights so x can take values from 0 to 8 and f(x) can take the values as follows:

$\begin{gathered} x=0,f(x)=10 \\ x=1,f(x)=30 \\ x=2,f(x)=50 \\ x=3,f(x)=70 \\ x=4,f(x)=90 \\ x=5,f(x)=110 \\ x=6,f(x)=130 \\ x=7,f(x)=150 \\ x=8,f(x)=170 \end{gathered}$

So the range is:

$\mleft\lbrace10,30,50,70,90,110,130,150,170\mright\rbrace$

Option B is correct.

What is the value of the expression a2 + b3 when a= 1/3 and b= 1/2 ?

Aleksandr-060686 [28]

Answer:

B. $\frac{17}{72}$

Step-by-step explanation:

${a}^{2} + {b}^{3} \\ \\ = \bigg( \frac{1}{3} \bigg)^{2} + \bigg( \frac{1}{2} \bigg)^{3} \\ \\ = \frac{1}{9} + \frac{1}{8} \\ \\ = \frac{8 + 9}{9 \times 8} \\ \\ = \frac{17}{72} \\$
