25 POINTS!!! Under a dilation centered at the origin, the vertex, (2, 3), of a polygon is moved to the point (−8, −12) . What is the scale factor of the dilation? Enter your answer in simplified form in the box.
325
Step-by-step explanation:
(x+8)2+(y+12)2=235The scale factor of the point will be ( 1 / 4).
What is a scale factor?The scale factor is defined as the proportion of the new image's size to that of the previous image. Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.
Given that under a dilation centered at the origin, the vertex, (2, 3), of a polygon is moved to the point (−8, −12).
The scale factor will be calculated as below:-
Scale factor = ( 2 / 8 ) = ( 1 / 4 )
Therefore, the scale factor of the point will be ( 1 / 4).

A family spent $93 at a carnival. They spent $18 on tickets to the carnival and $36 on food.They spent the rest of the money on games. Write and solve an equation representing how much money, in dollars, the family spent on games.
Answer:
$93-$18-$36=$39
$39
Step-by-step explanation:
Answer:
18 + 36 + 39 = 93 The family spent $39 on games.
Step-by-step explanation:
18 + 36 + g = 93
I'm using "g" to substitute the number of money they spent on games. To find what that is, you simply add 18 and 36.
18 + 36 = 54
So we know they used 54 dollars on tickets and food. Now we can take that away from the total amount spent.
93- 54 = 39
Here we can tell that the amount the family spent on games was 39 dollars. Or in other words, g = 39

Find the mistake in the following : 3 x ( 4 + 2 ) = 12 + 2
Answer: The mistake is improper use of distribution property.
Step-by-step explanation:
It is given that [tex]3\times (4+2)=12+2[/tex].
We need to find the mistake.
The given expression is
[tex]3\times (4+2)[/tex]
Using distribution property, we get
[tex]3\times (4)+3\times(2)[/tex]
[tex]12+6[/tex]
So, [tex]3\times (4+2)=12+6[/tex].
In the given calculation the 3 is not distributed properly because 3 is not multiplied with 2.
Therefore, the mistake is improper use of distribution property.

The graph of f(x) is shown below.
For each point (a,b) on the graph of y = f(x), the point ( 3a - 1, b/2) is plotted to form the graph of another function y = g(x). For example, (0,2) lies on the graph of y = f(x), so (3 * 0 - 1, 2/2) = (-1,1) lies on the graph of y = g(x).
(a) Plot the graph of y = g(x). Include the diagram in your solution.
(b) Express g(x) in terms of f(x).
(c) Describe the transformations that you would apply to the graph of y = f(x) to obtain the graph of y = g(x). For example, one transformation might be to stretch the graph horizontally by a factor of 5
(a) I have attached the graph.
(b) The function g(x) is given by g(x) = f(2x + 2)/3. You can work this out algebraically. You can also work this out by using the graph of the function.
(c) We can obtain the graph of y = g(x) from the graph of y = f(x) through the following transformations:
* stretch horizontally by a factor of 2
* stretch vertically by a factor of 3
* shift downwards by 2 units

Brooke and Lamont ran a half marathon, Brooke finished in 1 hour 45
minutes. Lamont finished in 115 minutes. Who had the faster time?
Answer: brooke had the faster time
Step-by-step explanation:
This is because if you convert 1 hour 45 into minutes it would be stated as 105 minutes and if you do 115 - 105 you are left with 10 which the bigger number is the fastest so it would be brooke the reason I subtracted was to see if they were not similar. Hope this helps :)
Brooke was the fastest because 115 minutes is very close to 2 hours. Therefore Lamont took longer.

scenarios is NOT a possible result?
1 point
a pair of same side interior angles with measures of 65 and 115°
a pair of alternate exterior angles with measures of 130 and 50°
a pair of supplementary angles with measures of 110' and 70°
a pair of corresponding angles with measures of 40° and 40°
Send me a copy of my responses.
Submit
Answer:
B. a pair of alternate exterior angles with measures of 130° and 50°
Step-by-step explanation:
Alternate exterior angles formed when two parallel lines are cut across by the same transversal line, are said to be congruent.
Therefore, a pair of alternate exterior angles cannot have different angle measures of 130° and 50°. Rather, both alternate exterior angles should be of equal measure of degree.
All other scenarios are possible result except option B: "a pair of alternate exterior angles with measures of 130° and 50°".
Option B is correct. "A pair of alternate exterior angles with measures 130 and 50degrees".
If two lines are cut by a transversal, line geometry is formed.
The following angles are formed by the transversal;
alternate interior and exterior anglesupplementary angles (sums up to 180degrees)pair of corresponding anglespair of vertically opposite angles (from intersection of two lines that formed X)Note that alternate exterior angles are obtuse angles (greater than 90 degrees). This statement falsifies the second option which says that "a pair of alternate exterior angles with measures 130 and 50degrees. 50 degrees" is an acute angle not obtuse.

Jocelyn compiled data on the number of hours students work per week the summer after senior year. The minimum number of hours in the distribution was 23. The range was 17. What is the maximum number of hours in the distribution?
Answer:
40
Step-by-step explanation:
The maximum number of hours in the distribution will be 40.
What is a range?A function's range is the collection of values it can take as input. After we enter an x value, the function outputs this sequence of values. The disparity between values in a data collection can be measured most simply using the range. The range can be calculated by simply disregarding the other values and subtracting the lowest value from the highest value.
Given that the minimum number of hours in the distribution was 23. The range was 17.
Range = Maximum number - Minimum number
17 = Maximum number - 23
Maximum number = 17 + 23
Maximum number = 40
Therefore, the maximum number of hours in the distribution will be 40.
