Graph the image of the figure after a dilation with a scale factor of 3 centered at (2, −7).
Use the Polygon tool to graph the quadrilateral by connecting all its vertices.
Answers
Answer:
Step-by-step explanation:
Each point moves 3 times the distance from the center of dilation that it was.
You can compute the new coordinates by ...
L = P - O . . . . . the length from O to P is P-O for some point P and origin O
Then 3 times that distance is
3L = 3P -3O
We want to find the point P' that is 3L from O, so we add this distance to the coordinates of O. We get ...
P' = 3L +O = 3P -3O +O
P' = 3P -2O
So, for the lower left point A(-2, -7), the dilated image point A' is ...
A' = 3(-2, -7) -2(2, -7) = (-6, -21) +(-4, 14) = (-10, -7)
That is, ...
A' = 3A +(-4, 14)
The coordinates of the remaining points can be found similarly.
___
On a graph, it is usually fairly easy to count the grid squares in each direction between the point of interest and the center of dilation. The image point is 3 times the distance in each direction (horizontally, vertically).

Complete the table using equivalent ratios.
Number of trees Number of cabins
10.5 5
__ 3
__ 7
Answers
Answer:
for seven cabins it should be 14.7 trees, im not sure about 3 cabins, sorry :(
Answer:
3) 6.3
7) 14.7
Step-by-step explanation:
Use ratios to solve the table
10.5/5 = x/3
cross multiply
31.5 = 5x
x = 6.3
10.5/5 = x/7
73.5 = 5x
x = 14.7
A train at a constant speed and goes 7.5 kilometers in 6 minutes. At the rate:
How far does the train go in 1 minute?
How far does the train go in 100 minutes?
Answers
Answer:
The distance covered by a train in 1 minute = 1.25 kilometers
The distance covered by a train in 100 minutes = 125 kilometers
Step-by-step explanation:
The distance covered = 7.5 kilometers
Time taken = 6 minutes
Calculating unit rate
unit rate = 7.5 kilometers / 6 minutes
= 1.25 kilometers per minute
Thus,
The distance covered by a train in 1 minute = 1.25 kilometers
and
The distance covered by a train in 100 minutes = 1.25 × 100
= 125 kilometers

Answer:
(a) On a coordinate plane, a rectangle has points (0, 0), (0, 1), (2, 0), (2, 1)
Step-by-step explanation:
Every point coordinate of the dilated figure will be smaller by the same factor.
Looking at the original (0, 3) coordinate, we find that possible answer choices include ...
A (0, 1) has a scale factor of 1/3
B (0, 4) has a scale factor greater than 1
C (0, 1) has a scale factor of 1/3
D (0, 2) has a scale factor of 2/3
__
Looking at the rest of the points in the answer selections, we find that the scale factors in choices C and D are not consistent from one point to another (or even within the same point). Those choices must be rejected.
In selection A, the image points are listed out of order, tending to confuse the issue. However, A is the correct choice.

Both widths are the same in a rectangle. So both are 6.5. Then you subtract 13 from 34. Now you are left with 21. No divide that by two to get your two lengths. That is l. L=10.5
Answer:
Step-by-step explanation:
P=2L+2W
P=34 W= 6.5
34=2L+2*6.5
34=2L+13
2L=21
L=10.5
or
Given:
P = 34 [Perimeter]
W = 6.5 {let's use W and L to make it easy to read]
Also known:
P = W + L + W + L = 2(W+L)
Fill in values:
34 = 2(6.5+L) [NOTE: This is an equation to determine the length (L) of the rectangle."]
. . .
17 = 6.5 + L [NOTE: This is a simplified form of the above equation.]
. . .
10.5 = L [NOTE: This is the solution (the value of L)]

Brandon says that the absolute value of a number and the opposite of a number is the same thing. Is Brandon correct? Use examples to help you explain.
Answers
Answer:
No, Brandon is not correct in making that statement
Step-by-step explanation:
No, Brandon is not correct in making that statement. The absolute value of a number is the total distance between that number and 0. Brandon most likely states this because the absolute value of a negative number such as -5 would actually be the opposite, which is 5. This is not true for the absolute value of a positive such as 5, which instead is actually just 5. Meaning that the absolute value of a positive integer is the same value and NOT the opposite.

An isosceles triangle has angle measures of (2x degrees) and (5x degrees). What are three possible angle measures of the triangle? Show all work.
Answers
Answer:
[tex]40^{\circ},\:40^{\circ},\: 100^{\circ}[/tex]
Step-by-step explanation:
The interior angles of any triangle always add up to [tex]180^{\circ}[/tex]. In an isosceles triangle, (at least) two sides are congruent and therefore their base angles are also congruent. We can then form the following equation:
[tex]2x+2x+5x=180[/tex], where [tex]x[/tex] is some constant.
Solving, we get:
[tex]9x=180,\\x=20[/tex]
Therefore, plugging our constant back in, our angles are:
[tex]2(20),\: 2(20), \: 5(20), \\\fbox{$40^{\circ},\:40^{\circ},\: 100^{\circ}$}[/tex].
Note this is only one group of possible angles. We could've also set the angle represented by [tex]5x[/tex] to be the pair of angles that are congruent, and depending on your definition of isosceles, each angle measure could be [tex]60^{\circ}[/tex] (equilateral).
Answer:
100, 40, 40
Step-by-step explanation:
First, do 2x+2x+5x because an isosceles triangle has two equal angles. We know that a triangle's total angle is 180 degrees so we do 180/9=20 x=20. Then multiply 2 by 20 to get 40. Then multiply 5 by 20 to get 100. So you get 40 40 100.
