Write the equation of the line passing through the point (-4 "-7)" and (8 "-17)"

kicyunya [14]

Answer:

$y = -\dfrac{5}{6} x -\dfrac{31}{3}$

In order to find equation:

<u>Find slope</u>:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} = \dfrac{rise}{run}$

$\rightarrow \sf slope: \dfrac{-17-(-7)}{8-(-4)}$

$\rightarrow \sf slope: -\dfrac{5}{6}$

Then find equation using:

y - y1 = m(x -x1) where (x1, y1) are points, m is slope

$\sf \rightarrow y - (-17) = -\dfrac{5}{6} (x - 8)$

$\sf \rightarrow y = -\dfrac{5}{6} x + \dfrac{20}{3} -17$

$\sf \rightarrow y = -\dfrac{5}{6} x -\dfrac{31}{3}$

Helppppp meeee pleaseeee in horrible at math

rosijanka [135]

Circumference = 2×3.14×r
3.14 is pie and r is the radius.
To find the radius you divide the diameter by 2.
19 ÷ 2 = 9.5
2×3.14×9.5 = 59.66
Multiply 59.66 by 6 because ther are 6 pennies.

59.66 × 6 = 357.96 mm.

A rectangle is 3 times as long as it is wide. if the area is 27 square feet, find its perimeter.

Marat540 [252]

W - a width
3w - a length
27 ft² - an area

Therefore:

w · 3w = 27
3w² = 27 |:3
w² = 9 → w = √9 → w = 3

3w = 3 · 3 = 9

width = 3
length = 9

The perimeter:

P = 2 · width + 2 · length

P = 2 · 3 + 2 · 9 = 6 + 18 = 24 ft.

Angle C and angle D are supplementary. If the measure of angle D is 84 degrees, what is the measure

garik1379 [7]

Suplementary is angles add up to 180 degrees

C=180-D

C=180-84

C=96 degrees

Hope this helped :)
