2. d

3. c

explanation

1. reflection, rotation, and dilations are all transformations

2. congruent shapes have to have the same shape and size, meaning they also have the same angle measures

3. sometimes, shapes may have the same area and perimeter but be different

Answer:

Possible answers 224 -2 23

Step-by-step explanation:

First, solve the inequality, but it is solved already in simplest form.

r can be anything less than or equal to 225

Possible answers 224 -2 23

As long as your answers are less than 225, it would be correct

Answer:

$y-1=\frac{1}{8}\left(x-7\right)$ is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Step-by-step explanation:

The endpoints:

B(6,9)

C(8,−7)

Calculating the Midpoint M of BC:

$\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)$

$\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)$

The Midpoint M of BC $=\left(\frac{8+6}{2},\:\frac{-7+9}{2}\right)$

$=\left(7,\:1\right)$

Calculating the slope of BC:

$\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)$

$m=\frac{-7-9}{8-6}$

$m=-8$

Given a line with slope $m$ then the slope of a

line perpendicular to it is:

$m_{prependicular}=-\frac{1}{m}=-\frac{1}{-8}=\frac{1}{8}$

Equation of line using point-slope form

$y-y_1=m\left(x-x_1\right)$

$y-1=\frac{1}{8}\left(x-7\right)$

Therefore, $y-1=\frac{1}{8}\left(x-7\right)$ is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Reasonableness. there are 53 students on a field trip. one chaperone is needed for every 6 students. how many chaperones are nee

xxMikexx [17]

To find out how many chaperones are needed we need to know the multiples of 6.
6<span>,12,18,24,30,36,42,48,54,60,66,72,78,84,90,96,102
Counting how many times 6's go into 53, we get 9.
We will need 9 chaperones!
I hope that helps!</span>
