Which line is perpendicular to a line that has a slope of -1/3?

Sliva [168]

Answer:

Option (c)

Step-by-step explanation:

Slope of a line that passing through two points M(-1, 4) and N(2, -5),

$m_1$ = $\frac{y_2-y_1}{x_2-x_1}$

= $\frac{-1-2}{4+5}$

= -( $\frac{3}{9}$ )

= - $\frac{1}{3}$

To find the line perpendicular line to MN we will use the property,

$m_1\times m_2=-1$

Where $m_1$ and $m_2$ are the slopes of two perpendicular lines.

Slope of line perpendicular to MN $(m_2)$ will be,

$-\frac{1}{3}\times m_2=-1$

$m_2=3$

Slope of line joining two points J(-3, -4) and K(3, -2),

Slope = $\frac{-4+2}{-3-3}=\frac{1}{3}$

Slope of line joining two points A(-3, 2) and B(3, 0)

Slope = $\frac{2-0}{-3-3}=-\frac{1}{3}$

Slope of the line joining points E(0, -3) and F(2, 3),

Slope = $\frac{-3-3}{0-2}$ = 3

Therefore, line EF is perpendicular to the line MN.

Option (c) is the answer.

The table shows the number of cell phone towers a

Olin [163]

Answer:

The correct option is;

B. Yes. The ratios of towers to customers (thousands) are all equivalent to a unit rate of 52 Towers/(Thousand customers)

Step-by-step explanation:

The given data can be presented as follows;

Cell Phone Towers

Customer (thousands) ${}$ Towers

1) 5.25 ${}$ 273

2) 6.25 ${}$ 325

3) 7.25 ${}$ 377

4) 9.25 ${}$ 481

From the given data, we have the ratio Towers/Customer (thousands) given as follows;

For 1), we have;

273 Towers/(5.25 thousands customers) = 52 Towers/(Thousand customer)

For 2), we have;

325 Towers/(6.25 thousands customers) = 52 Towers/(Thousand customer)

For 3), we have;

377 Towers/(7.25 thousands customers) = 52 Towers/(Thousand customer)

For 4), we have;

481 Towers/(9.25 thousands customers) = 52 Towers/(Thousand customer)

Therefore, the ratios of towers to customers (thousands) all have the same equivalent unit rate of 52 Towers/(thousand customers).

Drag the blue point to a place on the number line

sergejj [24]

Answer:

The number line is shown below.

Step-by-step explanation:

We need to represent number that is less than 3 on a number line.

Let x be numbers.

So, $x$ .

Now, we have a number which represents x<3. Here 3 is not included in the solution set, so there is an open circle on 3 and left side of 3 are in the solution set.

The number line is shown below.
