How to define a linear function?The slope-intercept equation for a linear function is presented as follows:
y = mx + b
In which:
m is the slope, which is the rate of change of the output variable y relative to the input variable x.b is the intercept, which is the value of y when x = 0.The line passes through the points (–1, –5) and (4, 5), hence the slope m is obtained as follows:
m = (5 - (-5))/(4 - (-1))
m = 2.
Hence:
y = 2x + b.
When x = -1, y = -5, hence the intercept b is obtained as follows:
-5 = -2 + b
b = -3.
Hence:
y = 2x - 3.
Then the value of a is obtained as the value of x when y = 1, hence:
2x - 3 = 1
2x = 4
x = 2.
The rate of change in the snowfall is given as follows:
m = (8.1 - 2.3)/2
m = 2.4 inches per hour.

Which is true about the solution to the system of inequalities shown? y > 3x + 1 y < 3x – 3 On a coordinate plane, 2 solid straight lines are shown. The first line has a positive slope and goes through (negative 2, negative 5) and (0, 1). Everything to the left of the line is shaded. The second line has a positive slope and goes through (0, negative 3) and (1, 0). Everything to the right of the line is shaded. Only values that satisfy y > 3x + 1 are solutions. Only values that satisfy y < 3x – 3 are solutions. Values that satisfy either y > 3x + 1 or y < 3x – 3 are solutions. There are no solutions.
There are no solutions to the system of inequalities Option (d)
Inequalities are a fundamental concept in mathematics and are commonly used in solving problems that involve ranges of values.
A system of two inequalities is a set of two inequalities that are considered together. In this case, the system of inequalities is
y > 3x + 1
y < 3x - 3
The inequality y > 3x + 1 represents a line on the coordinate plane with a slope of 3 and a y-intercept of 1. The inequality y < 3x - 3 represents another line on the coordinate plane with a slope of 3 and a y-intercept of -3. We can draw these lines on the coordinate plane and shade the regions that satisfy each inequality.
The first line has a positive slope and goes through (negative 2, negative 5) and (0, 1). Everything to the left of the line is shaded. The second line has a positive slope and goes through (0, negative 3) and (1, 0). Everything to the right of the line is shaded.
We can start by analyzing the inequality y > 3x + 1. This inequality represents the region above the line with a slope of 3 and a y-intercept of 1. Therefore, any point that is above this line satisfies this inequality.
Next, we analyze the inequality y < 3x - 3. This inequality represents the region below the line with a slope of 3 and a y-intercept of -3. Therefore, any point that is below this line satisfies this inequality.
To determine which values satisfy both inequalities, we need to find the region that satisfies both inequalities. This region is the intersection of the regions that satisfy each inequality.
When we analyze the regions that satisfy each inequality, we see that there is no region that satisfies both inequalities. Therefore, there are no values that satisfy the system of inequalities shown.
There are no solutions to the system of inequalities y > 3x + 1 and y < 3x - 3 by analyzing the regions that satisfy each inequality on a coordinate plane. The lack of a solution is determined by the fact that there is no region that satisfies both inequalities.

Which expression is a factor of both
x^2-9 and x^2+8x+15
Can you please explain this to me like you are talking to an elementary schooler, i kinda get it but im honestly so confused.
The expression that is a factor of both x² - 9 and x² + 8x + 15 is (x + 3).
What is the common factor between the given polynomials?Given the polynomials in the question:
x² - 9
x² + 8x + 15
To find a factor that is common to both x² - 9 and x² + 8x + 15, we can factorize the two expressions and look for any common factors.
First, factorize x² - 9:
Using the difference of sqaure formula
a² - b² = ( a + b )( a - b )
x² - 9
x² - 3² = (x - 3)(x + 3)
Next, factorize x² + 8x + 15:
Using AC method
( x + 3 )( x + 5 )
From the factorizations, we can see that both expressions have a common factor of (x + 3).

Which uppercase letters among W, X, Y, and Z have both
reflective and rotational symmetry?
Answer:
X
Step-by-step explanation:
Reflective symmetry, also known as mirror symmetry, exists when a figure can be reflected across a line and appear the same. Rotational symmetry exists when a figure can be rotated about a point by a certain degree less than 360 and still appear the same.
Among the uppercase letters W, X, Y, and Z:
The letter W has no reflective or rotational symmetry.
The letter X has both reflective and rotational symmetry. It's symmetrical on both the vertical and horizontal axes and has a rotational symmetry of 180 degrees.
The letter Y only has reflective symmetry on the vertical axis, but it does not have rotational symmetry.
The letter Z also has reflective symmetry on the horizontal axis, but it does not have rotational symmetry.
So among these letters, only X has both reflective and rotational symmetry.

The perimeter of the dilated rectangle M'N'O'P' is 54 centimeters.
If the area of the original rectangle is A, and the area of the dilated rectangle is A', then the relationship between their areas is:
A' = k² × A
Similarly, the relationship between their perimeters is:
P' = k × P
The original rectangle has an area of 14 square centimeters.
The dilated rectangle has an area of 126 square centimeters.
We need to find the perimeter of the dilated rectangle.
Let's denote the scale factor as "k."
126 = k² × 14
Dividing both sides by 14, we get:
9 = k²
k = 3
Now, we can find the perimeter of the dilated rectangle using the perimeter relationship:
P' = k × P
The original rectangle has a perimeter of 18 centimeters, so:
P' = 3 × 18

Suppose the prices of a certain model of new homes are normally distributed with a mean of 150,000 use the 68 9599.7 route to find the percentage of buyers who paid between 150,000 and 153,300 if the standard deviation is 1100
The percentage of buyers who paid between 150,000 and 153,300 is approximately 68% + 2.5% = 70.5%.
To solve this problem, we can use the properties of the normal distribution and the empirical rule (also known as the 68-95-99.7 rule) to estimate the percentage of buyers who paid between 150,000 and 153,300.
According to the empirical rule, given a normal distribution:
approximately 68% of the data falls within one standard deviation of the mean approximately 95% of the three standard deviations of the mean, the data are contained.
In this case, we want to find the percentage of buyers who paid between 150,000 and 153,300, which is one interval of length 3300 above the mean. To use the empirical rule, we need to standardize this interval by subtracting the mean and dividing by the standard deviation:
z1 = (150,000 - 150,000) / 1100 = 0
z2 = (153,300 - 150,000) / 1100 = 3
Here, z1 represents the number of standard deviations between 150,000 and the mean, and z2 represents the number of standard deviations between 153,300 and the mean.
Since the interval we are interested in is within three standard deviations of the mean (z2 <= 3), we can use the empirical rule to estimate the percentage of buyers who paid between 150,000 and 153,300:
Approximately 68% of the buyers paid within one standard deviation of the mean, which is between 149,000 and 151,000 (using z-scores of -1 and 1).
Approximately 95% of the buyers paid within two standard deviations of the mean, which is between 148,000 and 152,000 (using z-scores of -2 and 2).
Therefore, the remaining percentage of buyers who paid between 152,000 and 153,300 is approximately (100% - 95%) / 2 = 2.5%.
So, the percentage of buyers who paid between 150,000 and 153,300 is approximately 68% + 2.5% = 70.5%.

Please help me find the function that explains how to get the output from the input
Answer:
The equation for those inputs and outputs is:
0.25 *input - 151.75 = Output
Step-by-step explanation:
For this, first search for the Slope of the funtion
THe slope can be found by calculating this :
(y2-y1)/(x2-x1) or in this case (output2 - output1)/ (input2 - input1)
IT continues as follows:
( -48.5 - 24) / (-413 - (-703) ) =
= (-72.5) / (290)
= -0.25
The slope is -0.25. If the function is a line then the equation is
-0.25*input + B = output
with any of the choices we can determine B.
-0.25 * (-703) + B = 24
175.75 + B = 24
175.75 +B - 175.75 = 24 - 175.75
B = - 151.75
The equation for those inputs and outputs is:
0.25 *input - 151.75 = Output
Gabe learns more than just
math in Mrs. Zemla's class. Today he

investment because a car's value decreases
each year. So when Gabe was looking to
buy a 2024 Porsche Boxster for $54792,
he also reasearched the projected resale
value of the vehicle. He found that the
vehicle is expeced depreciate 19% each
year after the car is purchased. What is
the expected vaule of the car 7 years after
it was purchased?
The expected value of the car 7 years after it was purchased is $47,029.12.
To solve this problem, we need to calculate the expected value of the car after 7 years. To do this, we need to use the formula for calculating the value of a depreciating asset:
Value after n years = Initial Value - (Initial Value × (Depreciation Rate/100)×n)
In this case, the initial value of the car is $54792, the depreciation rate is 19%, and n = 7. Thus, the expected value of the car 7 years after it was purchased is:
Value after 7 years = 54792 - (54792 × (19/100)×7)
Value after 7 years = 54792 - (54792 × 0.19×7)
Value after 7 years = 54792 - 7762.88
Value after 7 years = $47,029.12
Therefore, the expected value of the car 7 years after it was purchased is $47,029.12.

Applying linear functions, we have: a. Bakery B charges a higher delivery fee b. Bakery A charges a higher price per cookie
c. Bakery B is cheaper.
How to Solve Linear Functions?In order to solve this problem, we will need to write the linear function for bakery A and bakery B.
Where:
b = the initial delivery fee which is the y-intercept
m = price per cookie
x = number of cookies
y = total cost
For Bakery A:
b = 5 (initial delivery fee)
m = price per cookie = change in y/change in x = 10 - 5 / 2 - 0
m = 5/2 = $2.5.
The linear function for bakery A is: y = 2.5x + 5.
For Bakery B:
b = 7 (initial delivery fee)
m = price per cookie = change in y/change in x = 16 - 7 / 4 - 0
m = 9/4 = $2.25.
The linear function for bakery A is: y = 2.25x + 7.
Therefore, we have:
a. The bakery that charges a higher delivery fee is Bakery B.
b. The bakery that charges a higher price per cookie is Bakery A.
c. Substitute x = 12 into both linear functions:
Bakery A: y = 2.5(12) + 5 = $35

x+3 is a factor of p(x)=x^3-7x^2+15x-9
true or false
The statement "x + 3 is a factor of p(x) = [tex]x^3 - 7x^2 + 15x - 9[/tex]" is false.
To determine whether x + 3 is a factor of p(x) = [tex]x^3 - 7x^2 + 15x - 9[/tex], we can use the factor theorem.
According to the factor theorem, if a polynomial p(x) has a factor (x - a), then p(a) = 0.
In this case, we have x + 3 as a possible factor. To check if it is indeed a factor, we substitute -3 for x in the polynomial p(x):
[tex]p(-3) = (-3)^3 - 7(-3)^2 + 15(-3) - 9[/tex]
= -27 - 63 - 45 - 9
= -144
Since p(-3) is not equal to zero, we conclude that x + 3 is not a factor of p(x).

First, you would separate the 2 shapes it consists of, a cylinder and a cone.
For the cone, you would use the equation (1/3)πr²h. Fill in the appropriate variables with the numbers from the formula. Pi, π, is a number itself so you leave it as it is.
r = radius = 8cm
h = height = 14cm
(1/3)(π)(8)²(14)
Put this equation into a calculator, it's important to include the parentheses or it might give you the incorrect answer, this is so that it separates the different values while multiplying. After inputting it, it should give you:
v = 938.289005872cm³
Then, you would have to find the volume of the cylinder, using the equation; πr²h.
The radius would be the same as the cone, and the height is as the problem states, 16cm.
Solve the problem after inputting the values:
π(8)²(16)= 3216.99087728cm³
Then, add the values to get the total volume.
938.289005872cm³ + 3216.99087728cm³ =

The top one is a triangular prism and uses the equation (1/2)bh.
b = base = 9m
h = 12m
(1/2)(9)(12) = 54m³
The bottom shape is a rectangular prism, where we use the equation L×W×H.
Length = 9m
Width = 9m
Height = 9m
Substitute the numbers into the equation.
9×9×9 = 729m³
Add both of them together to get the total volume:
54m³ + 729m³ = 783m³
#6 Equation:
In this figure, we are looking for the outer shape, so we will have to subtract the smaller cone.
First, we find the total volume, and we will use the same equation, (1/3)πr²h.
radius = half of diameter = 20/2 = 10mm
h = 20mm
(1/3)π(10)²(20) = 2094.39510239mm³
Second, we find the volume of the smaller cone, using the same equation, (1/3)πr²h.
In order to find the diameter, we will have to subtract the 7 mm that are on either side of the cone, so 20 - 14 = 6, then divide it by 2 so we can get the necessary radius. 6/2 = 3
r = 3mm
h = 14mm
Substitute values into equation and use calculator to solve.
(1/3)π(3)²(14) = 131.946891451mm³
Subtract the value of the smaller cone from total volume in order to get the volume for this figure.
2094.39510239mm³ - 131.946891451mm³ =
1962.44821094mm³
Raj purchases a new home for $150,000. The value of the home increases by 9% every 3 years.
Determine the value of the home after 5 years.
The value of the home after 5 years would be $194,415.
How to calculate the value of the home after 5 years
First, let's calculate the increase in value for each 3-year period:
After the first 3 years:
Increase = 9% of $150,000 = 0.09 * $150,000 = $13,500
After the second 3 years:
Increase = 9% of ($150,000 + $13,500) = 0.09 * ($150,000 + $13,500) = $14,850
After the third 3 years:
Increase = 9% of ($150,000 + $13,500 + $14,850) = 0.09 * ($150,000 + $13,500 + $14,850) = $16,065
Now, let's add these increases to the initial value of the home to find the value after 5 years:
Value after 5 years = $150,000 + $13,500 + $14,850 + $16,065 = $194,415
Therefore, the value of the home after 5 years would be $194,415.

Alfred says that the line shown on the scatter plot is a good line of fit because the line goes through the middle of all the data points. Do you agree? Explain your reasoning
No, I disagree because a good line of fit has to minimize the sum of the squared distance between all the points in the data.
Line of fitA line of fit is used to mathematically model the relationship between variables in a data. A line of fit is drawn such that the best line would minimize the sum of the squared distances between the plotted points.
This means that, the line of fit should not aim to go through the middle of the data points but minimize the sum of the squared distances between them.
Hence, Alfred's reasoning is Incorrect .

The value of side TS is,
⇒ TS = 28
First, we are going to divide the figure and named new points X and Y as:
Now, we know that TS is the sum of TX and XS.
TS = TX + XS
Additionally, TX has the same length of HJ, so:
TX = HJ = 14
Now, we want to know the length of YK, and we can calculate it using the following equation:
LK = LY + YK
LY = HJ,
so, LY = 14
And, 42 = 14 + YK
42 - 14 = YK
28 = YK
Finally, since T and S are midpoints, the length of XS is the half of the length of YK. It means that XS is:
XS = YK/2
XS = 28/2
XS = 14
Therefore, TS is equal to:
TS = TX + XS
TS = 14 + 14
TS = 28

The critical values t₀ for a two-sample t-test is ± 2.0.6
To find the critical values t₀ for a two-sample t-test to test the claim that the population means are equal (i.e., µ₁ = µ₂), we need to use the following formula:
t₀ = ± t_(α/2, df)
where t_(α/2, df) is the critical t-value with α/2 area in the right tail and df degrees of freedom.
The degrees of freedom are calculated as:
df = (s₁²/n₁ + s₂²/n₂)² / [(s₁²/n₁)²/(n₁-1) + (s₂²/n₂)²/(n₂-1)]
n₁ = 14, n₂ = 12, X₁ = 6,X₂ = 7, s₁ = 2.5 and s₂ = 2.8
α = 0.05 (two-tailed)
First, we need to calculate the degrees of freedom:
df = (s₁²/n₁ + s₂²/n₂)² / [(s₁²/n₁)²/(n₁-1) + (s₂²/n₂)²/(n₂-1)]
= (2.5²/14 + 2.8²/12)² / [(2.5²/14)²/13 + (2.8²/12)²/11]
= 24.27
Since this is a two-tailed test with α = 0.05, we need to find the t-value with an area of 0.025 in each tail and df = 24.27.
From a t-distribution table, we find:
t_(0.025, 24.27) = 2.0639 (rounded to four decimal places)
Finally, we can calculate the critical values t₀:
t₀ = ± t_(α/2, df) = ± 2.0639
