Answer:

No.

Step-by-step explanation: the 2 is repeated and an x-axis can't be repeated

No, it doesn't. A function cannot have two x-values repeat, and this table has 2 multiple times. The answer is C.

Hope this helped!

- (4, 5) and (4, -2) -

We can find the slope by using rise/run

m=\frac{y_2-y_1}{x_2-x_1}\\m=\frac{5-(-2)}{4-4}  \\

As expected, the slope is indeed undefined. The denominator can't be 0 but this one has denominator that's 0 which is undefined.

Meaning that, when the x-value for both ordered pairs are the same, the slope will be undefined.

For the graph, It should be like this below in the picture.

David y Angie tienen dos cartulinas iguales. David corta la suya en 3 trozos iguales y Angie la corta en 7 trozos. Los dos usan
Bess [88]

Answer:

(i) David ha empleado \frac{2}{3} de la cartulina.

(ii) Angie ha empleado \frac{2}{7} de la cartulina.

(iii) David ha usado más cartulina.

Step-by-step explanation:

El problema indica que David y Angie emplean una cartulina del mismo tamaño cada uno. David corta la suya en 3 pedazos iguales, mientras que Angie obtiene 7 pedazos iguales. Finalmente, cada uno emplea dos de sus pedazos. A continuación, respondemos a las preguntas del enunciado:

(i) <em>¿Qué fracción de cartulina ha usado David?</em>

La fracción de cartulina empleada por David es igual a los pedazos utilizados divididos por el total de pedazos. Esto es:

x = \frac{2}{3}

David ha empleado \frac{2}{3} de la cartulina.

(ii) <em>¿Qué fracción de cartulina ha usado Angie?</em>

Aplicando el mismo procedimiento del punto anterior, tenemos que:

x = \frac{2}{7}

Angie ha empleado \frac{2}{7} de la cartulina.

(iii) <em>¿Quién ha usado más cartulina?</em>

La persona que ha usado la mayor cantidad de cartulina es aquella que tiene el menor denominador. Por tanto, David ha usado más cartulina.

What is 0.0027 in scientific notation?
Nata [24]
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the <span>1010</span>. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.<span>2.7×<span>10<span>−<span>3</span></span></span></span>
