Hi can someone please help me solve the following system of inequalities and state the coordinates in the solution setz
Answers
The graph of the system of the inequalities is attached.
To graph the inequalities y < -x - 4 and y ≥ (3/5)x + 4, we can start by graphing the corresponding equations and then shade the appropriate regions based on the inequality signs.
Let's begin with the equation y = -x - 4:
Choose a range of x-values to plot.
For simplicity, let's use x-values from -10 to 10.
Substitute different x-values into the equation to find corresponding y-values.
For example:
When x = -10, y = -(-10) - 4 = 10 - 4 = 6.
When x = 0, y = -(0) - 4 = -4.
When x = 10, y = -(10) - 4 = -10 - 4 = -14.
Plot these points on the coordinate plane and draw a straight line passing through them.
This line represents the equation y = -x - 4.
Next, let's graph the equation y = (3/5)x + 4:
Again, choose a range of x-values to plot. Let's use the same range of -10 to 10.
Substitute different x-values into the equation to find corresponding y-values. For example:
When x = -10, y = (3/5)(-10) + 4 = -6 + 4 = -2.
When x = 0, y = (3/5)(0) + 4 = 0 + 4 = 4.
When x = 10, y = (3/5)(10) + 4 = 6 + 4 = 10.
Plot these points on the coordinate plane and draw a straight line passing through them.
This line represents the equation y = (3/5)x + 4.
Now, let's shade the regions based on the inequalities:
For y < -x - 4, we need to shade the region below the line y = -x - 4.
For y ≥ (3/5)x + 4, we need to shade the region above or on the line y = (3/5)x + 4.
Hence, the region where the shaded regions overlap represents the solution to both inequalities.

The significance of sample size in statistical experiments cannot be overstated. A larger Sample size enhances the reliability and generalizability of the results, reducing sampling errors and increasing statistical power.
Sample size is a critical aspect of statistical experiments that significantly impacts the reliability of the results. It represents the number of individuals, observations, or data points included in a study. Understanding the significance of sample size is essential for ensuring the validity and generalizability of statistical findings.
The size of the sample directly influences the precision and accuracy of the estimates or conclusions drawn from the data. A larger sample size generally leads to more reliable results by reducing sampling errors and increasing the representativeness of the population under study. With a larger sample, the estimates are likely to be closer to the true values, providing greater confidence in the findings.
When the sample size is small, the variability in the data may be magnified, making it challenging to draw accurate conclusions. Results obtained from a small sample may not adequately capture the diversity or complexity of the population, leading to biased or misleading findings. This is known as sampling error, where the sample does not fully reflect the characteristics of the larger population.
Moreover, the statistical power of an experiment is directly related to the sample size. Statistical power refers to the ability of a study to detect true effects or relationships between variables. A larger sample size increases the power of the analysis, allowing researchers to identify smaller, yet meaningful, differences or associations. In contrast, a small sample size may result in low statistical power, making it difficult to detect significant effects even if they exist.
It is important to note that sample size requirements can vary depending on the research design, objectives, and the anticipated effect size. Complex studies or analyses involving rare events or small effect sizes may require larger sample sizes to achieve sufficient power and precision.
In conclusion, the significance of sample size in statistical experiments cannot be overstated. A larger sample size enhances the reliability and generalizability of the results, reducing sampling errors and increasing statistical power. Researchers should carefully consider sample size calculations to ensure their studies yield robust and trustworthy conclusions.

the line with a slope of 9/7 & containing a midpoint of the segment whose end points are (2, -3) & (-6, 5)
Answers
1. Find the midpoint of the segment using the midpoint formula:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
Midpoint = ((2 + (-6)) / 2, (-3 + 5) / 2)
Midpoint = (-4 / 2, 2 / 2)
Midpoint = (-2, 1)
2. Use the midpoint and the slope to find the equation of the line in point-slope form. The point-slope form is given by:
y - y1 = m(x - x1), where (x1, y1) is the midpoint and m is the slope.
Substituting the values:
y - 1 = (9/7)(x - (-2))
y - 1 = (9/7)(x + 2)
y - 1 = (9/7)x + (18/7)
3. Simplify the equation to obtain the slope-intercept form:
y = (9/7)x + (18/7) + 1
y = (9/7)x + (18/7) + (7/7)
y = (9/7)x + (25/7)
So, the equation of the line with a slope of 9/7 and containing the midpoint of the segment with endpoints (2, -3) and (-6, 5) is y = (9/7)x + (25/7).
Answer:Therefore, the equation of the line with a slope of 9/7 and containing the midpoint of the line segment with endpoints (2, -3) and (-6, 5) is:
y = (9/7)x + 25/7.
Step-by-step explanation:Step 1: Find the midpoint of the line segment.
The midpoint formula is given by:
Midpoint = ((x1 + x2) / 2, (y1 + y2) / 2)
Given the endpoints of the line segment as (2, -3) and (-6, 5), we can find the midpoint as follows:
Midpoint = ((2 + (-6)) / 2, (-3 + 5) / 2)
Midpoint = (-4 / 2, 2 / 2)
Midpoint = (-2, 1)
So, the midpoint of the line segment is (-2, 1).
Step 2: Write the equation of the line using the slope-intercept form.
The slope-intercept form of a line is given by:
y = mx + b
where m is the slope and b is the y-intercept.
Given the slope as 9/7, we have:
y = (9/7)x + b
Step 3: Substitute the coordinates of the midpoint to find the value of b.
Using the coordinates of the midpoint (-2, 1), we can substitute these values into the equation:
1 = (9/7)(-2) + b
1 = -18/7 + b
To find the value of b, we can solve this equation:
1 + 18/7 = b
25/7 = b
Step 4: Write the final equation of the line.
Using the value of b, the equation becomes:
y = (9/7)x + 25/7

Hope this helps!
Answer:
y = - 1/2 x + 2
Step-by-step explanation:
Main concepts:
1. Slope intercept form of Equation for a line
2. ordered pairs
3. Finding the y-intercept
4. Finding slope
5. Finding the equation for our line
1. Slope intercept form of Equation for a line
For any non-vertical line, the equation can be written in "slope-intercept" form: [tex]y=mx+b[/tex] where b is the y-coordinate of the y-intercept of the line, m is the "slope" of the line, and x & y are the (x,y) coordinates of any point you choose on the line.
2. ordered pairs
Any point on the coordinate system (whether on the line or not) is defined by an (x,y) coordinate pair. All points are measured starting from the origin (0,0).
The "x-coordinate" is the distance to the left or right of the origin, and the "y-coordinate" is the distance above or below the origin.
3. Finding the y-intercept
The y-intercept of a line is the place where the line crosses the "y-axis" (the vertical axis). Notice that the blue line crosses the y-axis at a height of 2, so the y-intercept is (0,2), and [tex]b=2[/tex]
4. Finding slope
The slope of any non-vertical line can be found from two known points [tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex] using the following formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Both to minimize error to to work with "nicer" numbers, try to choose points that are crossing through the intersection of grid lines (but any two points will work). Two points that are fairly easy to identify on this line are (0,2) and (4,0). (these two points are the y-intercept that we already identified, and the place where the blue line crosses the horizontal axis -- called the x-intercept).
Substituting into the formula:
[tex]m=\dfrac{(0)-(2)}{(4)-(0)}[/tex]
[tex]m=\dfrac{-2}{4}[/tex]
[tex]m=-\frac{1}{2}[/tex]
5. Finding the equation for our line
Knowing both the y-intercept and the slope, we can now substitute the values into the equation and get the equation for this line:
[tex]y=- \frac{1}{2}x+2[/tex]
Which statement applies to the transformed function f(x)−4
?
Answers
The function is odd, and the graph would be shifted downward. option(2)
The statement "f(x) - 4" represents a transformation applied to the original function f(x). This transformation involves subtracting 4 from the values of the function f(x) for all x. In other words, it shifts the entire graph of f(x) downward by 4 units along the y-axis.
Specifically, each y-value of the original function f(x) is reduced by 4. For example, if the original function had a point (x, y), the transformed function f(x) - 4 would have the corresponding point (x, y - 4). This means that every point on the graph is shifted downward by 4 units.
This transformation affects the overall shape, position, and properties of the function. The new graph will have the same general shape as the original, but it will be translated downward. If there were any intercepts or turning points in the original function, they will also be shifted downward by 4 units.

Calista was told that she had an average grade of an 82, but not told what she got on her 6th assignment. Calista knows that she got a 62, 88, 92, 74 and 78 on the other 5 assignments.
What was Calista's grade on her last assignment?
Answers
Calista's grade on her last assignment is 98.
To determine Calista's grade on her last assignment, we can calculate the average grade using the given information.
The sum of Calista's grades on the first five assignments is: 62 + 88 + 92 + 74 + 78 = 394.
Since the average grade is given as 82, we can find the total sum of all six assignments by multiplying the average grade by the number of assignments, which is 6: 82 * 6 = 492.
To find Calista's grade on her last assignment, we subtract the sum of her grades on the first five assignments from the total sum: 492 - 394 = 98.

Loan comparison
Answers
Loan 1 would require more money over the time of the loan.
Does more time mean that you pay back more money on a loan at a given interest rate?When you borrow money, the lender assesses interest as compensation for letting you use their resources. The principal, or the amount borrowed initially, and the length of time it takes to repay the loan are used to compute interest. Interest must accumulate over a longer length of time the longer the repayment duration.
The number of interest accrual periods rises as a result of extending the payback period, which raises the total amount of interest paid. The total interest paid over a longer term will be larger than over a shorter period even if the interest rate stays the same.

tebogo is a street vendor who buys blankets from a wholesaler for R60 per blanket.he is restricted to 50 blankets per month.his total costs include a monthly delivery fee of R120 and rent for selling space .calculate his total cost per month
Answers
Answer:
here is not much information
Step-by-step explanation:
To calculate Tebogo's total cost per month, we need to consider the cost of blankets, delivery fee, and rent for selling space.
Cost of blankets:
Tebogo buys blankets from the wholesaler at R60 per blanket. Since he is restricted to 50 blankets per month, the cost of blankets is calculated as follows:
Cost of blankets = R60 per blanket x 50 blankets = R3000
Monthly delivery fee:
Tebogo incurs a monthly delivery fee of R120.
Rent for selling space:
The rent for selling space is not provided in the given information. To calculate the total cost per month, we would need the specific amount for rent.
To determine the total cost per month, we can sum up the costs:
Total cost per month = Cost of blankets + Monthly delivery fee + Rent for selling space
However, since the rent for selling space is not provided, we cannot calculate the exact total cost per month without that information.

Answers
The most appropriate chart to depict US energy consumption would be a pie chart since a pie chart helps to see the composition of different proportions representing total consumption.
How to explain the chartsChart A is not appropriate because a line graph is used to depict information to analyze changes over time or over a period. However, to show the energy consumption, the line graph is not an accurate depiction since the type of energy source is a categorical variable.
Chart B is also appropriate because it is a column graph and such type of graphs are used to represent categorical variables. The US energy consumption can be represented well through a column graph as it well depicts the highest consumption source and the lowest consumption source.
Yes more than one kind of display would therefore be acceptable as we can use to show the information through both a pie chart and a column graph.
