The "slope" of a vertical line. A vertical line has undefined slope because all points on the line have the same x-coordinate. As a result the formula used for slope has a denominator of 0, which makes the slope undefined..

Answer:

mean = 5.4

median = 5

mode = is the number that appears the most answer = 5

Step-by-step explanation:

mean

5+6+6+9+10+4+2+5+7+6+7+3+5+5+5+4+9+2+10 = ......... / 19 = 5.4

median

2 2 3 4 4 5 5 5 5 5 6 6 6 7 7 9 9 10 10 then find the middle between these = 5

Write the standard form of the equation of the line that passes through point at (4,2) and is parallel to whose equation is y=2x

solong [7]

Since the equation is parallel to y=2x-4 that means they have the same slope. Now that you have the slope and fortunately a point, you can solve this by using point slope formula
$y - y1 = m(x - x1)$
Which is what I did on the attached picture and just rearrange it after solving to Ax+By=C/2x-y=6

Find the slope of the line through each pair of points.

Natali [406]

Answer:

1. 0, 2. -1/2, 3.undefined, 4. -5/3, 5. 6, 6. -2, 7. 23/17

Step-by-step explanation:

y2 - y1 / x2 - x1

1. -18 - -18 / 15 - 6 = 0

2. 16 - 12 / 0 - 8 = -4/8 = -1/2

3. 37 - 2 / -15 - -15 is undefined (can't have 0 as denominator)

4. 30 - 20 / -5 - 1 = 10 / -6 = -5/3

5. -36 - -12 / 4 - 8 = -24 / -4 = 6

6. - 23 - -15 / 11 - 7 = -8 / 4 = -2

7. 100 - 54 / -38 - -72 = 46 / 34 = 23/17

The triangles ABD, ADC and ABC are similar (AA stands for "angle, angle" and means that the triangles have two of their angles equal).

If two triangles have two of their angles equal, the triangles are similar.

Therefore the sides of triangles are in proportion.

$\dfrac{c}{6}=\dfrac{2}{c}$

cross multiply

$c\cdot c=6\cdot2\\\\c^2=12\to c=\sqrt{12}$

Use the Pythagorean theorem for calculate x:

$x^2=2^2+(\sqrt{12})^2\\\\x^2=4+12\\\\x^2=16\to x=\sqrt{16}\to\boxed{x=4}$
