Answer:

$-1.4$

Step-by-step explanation:

The slope of a line is the change in the line. It can be found using the formula;

$\frac{rise}{run}$ or $\frac{y_2-y_1}{x_2-x_1}$ .

Substitute in the given points, and solve for the slope;

$\frac{y_2-y_1}{x_2-x_1}\\\\= \frac{2-9}{11-6}\\\\= \frac{-7}{5}\\\\= -1.4$

Answer:

-7/5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(2-9)/(11-6)

m=-7/5

Tiffany sees this given dilation and claims that the scale factor is 2

Alenkinab [10]

Answer:

The scale factor is not 2

Step-by-step explanation:

Given

See attachment for the dilated triangles

Triangle ABC is dilated through center point O to form triangle A'B'C'.

From the attachment, we have:

$OC = 2$ i.e. the distance from the center point to C

and

$OC' = 6$ i.e. the distance from the center point to C'

The length of OC' is calculated using:

$OC' = OC + CC'$

$OC' = 2 + 4$

$OC' = 6$

The scale factor (k) is then calculated by dividing OC' by OC

$k = \frac{OC'}{OC}$

$k = \frac{6}{2}$

$k = 3$

Hence, Tiffany's claim is incorrect.

x = 1

Answer:

$m\angle XVW = 100\degree$

Step-by-step explanation:

In the first figure, FP is the bisector of $\angle DFE$

$\therefore m\angle 1 = m\angle 2\\\therefore 44x + 1 = 46x - 1\\\therefore 1 + 1 = 46x - 44x\\\therefore 2 = 2x\\\therefore \frac{2}{2} = x \\\huge \red {\boxed {\therefore x = 1}}$

In the second figure, VP is the bisector of $\angle XVW$

$\therefore m\angle 1 = m\angle 2\\\therefore 12x + 2 = 11x +6\\\therefore 12x - 11x = 6 - 2\\\therefore x = 4\\\because m\angle XVW = m\angle1 + m\angle 2\\\therefore m\angle XVW = 12x + 2 + 11x +6\\\therefore m\angle XVW = 23x + 8\\\therefore m\angle XVW = 23\times 4+ 8\\\therefore m\angle XVW = 92+ 8\\\huge \purple {\boxed {\therefore m\angle XVW = 100\degree}} \\$
