If anyone knows the answer to this can you help me
Murljashka [212]

Answer:

<h3>             C.    y + 7 = -7(x - 3)</h3>

Step-by-step explanation:

The equation of a line is:

                          y - y₀ = m(x - x₀)

where <em>m</em> is the slope and <em>(x₀, y₀)</em> is the point which the line passes through

The product of slopes of two perpendicular lines is  -1

so if given lines slope is ¹/₇ them:

     ¹/₇·m = -1

        m = -7

(3, -7)     ⇒    x₀ = 3,  y₀ = -7

Therefore:

               y - (-7) = -7(x - 3)

                <u> </u><u>y + 7 = -7(x - 3) </u>

* 4. A circle is divided into ten equal sectors.
Fiesta28 [93]

Answer:

a. Find the measure of each central angle.

The central angle of a circle = 360 °

Now Pie is cut into 10 equal sectors

Angle of each sector is given by

Angle of sector = Total central angle/number of sectors

=  {360}^{0}  \div 10

=  {36}^{0}

Hence , the central angle of one slice of pie is 36°

b. If the diameter is 50 in., find the length of an arc of one of the sectors.

length of an arc of one of the sectors =

= \frac{1}{n}  \times 2\pi \times r

= \frac{1}{10}  \times 2\ \frac{22}{7}  \times 50

= 31.42 \: in

A proportional relationship is shown in the table below: what is the slope and what numbers do i graph. ty besties
dangina [55]

Answer:

The slope of the line is m = \frac{3}{5} and the equation of the line is y = \frac{3}{5}\cdot x.

Step-by-step explanation:

From table we understand that slope of the line is constant, that is, for each change of x there is one and only change in y, fulfilling the main characteristic of a line and we can determine the slope for every point of the line by means of the following expression:

m = \frac{y_{f}-y_{o}}{x_{f}-x_{o}} (1)

Where:

x_{o}, x_{f} - Initial and final x-coordinates of the line.

y_{o}, y_{f} - Initial and final y-coordinates of the line.

If we know that (x_{o}, y_{o}) = (0,0) and (x_{f},y_{f}) = (8,4.8), then the slope of the line is:

m = \frac{4.8-0}{8-0}

m = \frac{3}{5}

From graph we conclude that x-intercept of the line is b = 0. Hence, the equation of the line is y = \frac{3}{5}\cdot x and we proceed to plot the expression with the help of a graphing tool.
