a) Just add 1 square on the right and 1 square on top for figure 4. Add 1 more in each place for figure 5.
b) Each stage adds a square above and a square to the right. The pattern never decreases. This trend is shown by figures 1, 2, and 3.
c) Figure 0 would be a single square. Simply follow the pattern in reverse. As the figure number decreases, squares are removed from the right and the top rather than added.
What is the value of x in the equation –2.4x = 8.4?
1. –20.16
2. –3.5
3. 3.5
4. 20.16
Answer:
2. -3.5
Steps:
divide both sides by by (-2.4): -2.4x ÷ (-2.4) = 8.4 ÷ (-2.4)
any equation divided by itself equals 1 so that would be the right side: x = 8.4 ÷ (-2.4)
divide the equation on the left and get: x = -3.5

Mrs. Li wants to compare her students’ test scores to the school average. She created a table to help her. Mrs. Li’s Student Test Scores Student Score compared to school average Adam +3 Bryan 0 Cierra –4 Devaughn +1 Elena +5 Fionna –2 Which list orders the students by lowest score to highest score? Bryan, Cierra, Fionna, Devaughn, Adam, Elena Cierra, Fionna, Bryan, Devaughn, Adam, Elena Elena, Adam, Devaughn, Bryan, Fionna, Cierra Bryan, Devaughn, Fionna, Adam, Cierra, Elena (on edge)
Answer:
B
Step-by-step explanation:
The given differences between the test scores of Mrs. Li's students and the average test score of the school give us the order from lowest to highest marks of Mrs. Li's students as Cierra, Fionna, Bryan, Devaughn, Adam, and Elena. Hence, the 2nd option is the right choice.
What is average of data?The average of data is the ratio of the sum of all observations in the data to the number of observations in the data. It can be written as:
[tex]\overline{x} = \frac{\sum x}{N}[/tex]
where [tex]\overline{x}[/tex] represents the average, x represents the observations, and N represents the number of observations.
How to solve the given question?In the question, we are given the comparison of the test scores between Mrs. Li's students and the school's average test score.
The data is as follows: Adam +3 Bryan 0 Cierra –4 Devaughn +1 Elena +5 Fionna –2, where the shown figure is the difference between their respective score and the average test score of the school.
We are asked to identify the order from the given lists that show the students in order from lowest marks to highest marks.
A negative data means a score less than the average score.
Therefore, Cierra and Fionna got a score less than the average score, with Cierra scoring the least.
A data = 0 means a score equal to the average score.
Therefore, Bryan got a score equal to the average score.
A positive data means a score more than the average score.
Therefore, Adam, Devaughn, and Elena got a score more than the average score, with Elena getting the highest followed by Adam and the Devaughn.
Therefore the order looks like this: Cierra, Fionna, Bryan, Devaughn, Adam, and Elena, which is the 2nd option.

pizzas cost $8 plus a $3 delivers charge Show the cost of 1, 2, 3 and 4 pizzas. is there a direct variation? ASAP
Step-by-step explanation:
Write an equation.
c= the cost
p= the number of pizzas
8p means $8 per pizza
And adding 3 includes the delivery charge.
c=8p+3
Plug in the numbers 1-4.
1: $11
2: $19
3: $26
4: $35
This equation is NOT a direct equation since you have to add 3 (for the delivery charge) to the numbers.

x +4 =5
Subtract 4 from each side
x+4-4 =5-4

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

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).

R is between S and T. RS = 5x – 13, RT = 2x + 5, and ST = 3x + 24.
Find the value of x and ST.
S
R.
Answer:
The value of x is 8, and m<ST = 48 degrees.
Step-by-step explanation:
With the given information, we know the worth of each angle. To solve it, an equation must be made.
RS (part) + RT (part) = ST (whole)
Should look like this: 5x - 13 + 2x + 5 = 3x + 24.
Then solve the equation.
First, add up all that has in common:
Should look like: 7x - 8 = 3x + 24
Then move 3x from the right to the left by subtraction.
Should look like: 4x - 8 = 24
Next, move the 8 to the other side by addition.
Should look like: 4x = 32
Finally, to find what the value of x is, divide 4 on both sides.
You should get an answer of x = 8.
To find the measurement of ST, replace the x in 3x + 24.
3(8) + 24 = 48.
m<ST = 48 degrees.
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.

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
