Which two points lie on a line with an undefined slope?

2 answers:

6 0

The formula for slope is
m = (y2 - y1)/(x2 - x1)

A. m = (5 - 0)/(-2 + 2)
m = (5)/(0)
m = error

B. m = (-2 - 0)/(0 + 2)
m = (-2)/(2)
m = -1

C. m = (2 - 0)/(2 - 0)
m = (2)/(2)
m = 1

D. m = (0 - 0)/(2 - 3)
m = (0)/(-1)
m = 0

the slope that is deemed undefined is the one resulting in an error, which is A

Response:

Answer A. $(-2,0)$ and $(-2,5)$

Detailed explanation:

It is known that

A vertical line has an undefined slope

Lines that run parallel to the y-axis are vertical lines

Points on a vertical line share the same x-coordinate

In this case

the points $(-2,0)$ and $(-2,5)$ share the same x-coordinate

thus

The points lie on a vertical line which has an undefined slope

Chelsea has 11 times as many art brushes as Monique. If they have 60 art brushes altogether, how many brushes does Chelsea have?

zzz [12365]

Let Monique have m brushes.
Chelsea then has <span>11m brushes because she has 11 times as many as Monique. Together they total 60 brushes, so we form the equation:

m+11m=60.

Thus 12m=60, and dividing both sides by 12 gives m=5.

Chelsea has 11m=11*5=55 brushes.

1/16 2/16 3/16 4/16 5/16 6/16 7/16 8/16 9/16 10/16 11/16 12/16

Explicación paso a paso:

Para identificar las brocas existen dos aspectos a considerar:

1.- Las fracciones que comparten el mismo denominador aumentan en orden ascendente a medida que los numeradores incrementan, lo que significa que entre

9/16 3/16 7/16 5/16 11/16 el orden sería (de menor a mayor)

3/16 5/16 7/16 9/16 11/16

2.- Fracciones con diferentes denominadores pueden convertirse a un denominador común /16 multiplicando la fracción, por ejemplo

1/4 = 1*4/4*4 = 4/16

Aplicando este método, todas las fracciones se transforman al formato mencionado previamente y se organizan

1/4 = 4/16

3/8 = 6/16

1/2 = 8/16

5/8 = 10/16

1/8 = 2/16

Por lo tanto, hay diez brocas, comenzando con 1/16 hasta la número 12 que es 12/16

Finalmente, el orden sería:

1/16 2/16 3/16 4/16 5/16 6/16 7/16 8/16 9/16 10/16 11/16 12/16

In year 3 it is expected that the total value of clothing sales will reach 32 million if the total value of ASCO sells Remains t

tester [12383]

Answer:

The sales figure for the third year is $[\frac{32\ \text{mn}-x\ \text{mn}}{x\ \text{mn}}\times 100\%]$ .

Step-by-step explanation:

Since sales data for the second year is unavailable, we denote it as x million.

Year 3's total sales amount to 32 million.

Calculate the sales account for year 3 as follows:

$\text{Percentage of sales for year 3}=\frac{\text{Total Sales in year 3}-\text{Total Sales in year 2}}{\text{Total Sales in year 2}}\times 100\%$

$=\frac{32\ \text{mn}-x\ \text{mn}}{x\ \text{mn}}\times 100\%$
