Answer:

Is a consistent independent system

Step-by-step explanation:

we have

[tex]-x-y=7[/tex] -----> isolate the variable y

[tex]y=-x-7[/tex] ----> equation A

[tex]5x-5y=5[/tex] -----> isolate the variable y

[tex]y=x-5[/tex] ---> equation B

Compare equation A and equation B

We can affirm that

The slopes are not equal ( so the lines are not parallel)

The lines are different

The product of their slopes is equal to -1 (the lines are perpendicular)

so

The system of equations has only one solution

therefore

Is a consistent independent system

By analyzing the given equations and rewriting them to compare coefficients, it is clear that the system of equations is independent because they have different slopes and will intersect at exactly one point.

To classify the system of equations as independent, dependent, or inconsistent without graphing, we have to analyze the equations and solve for their relation to each other. The given equations are:

-x - y = 7
5x - 5y = 5

We can start by putting the equations in the same form to compare the coefficients:

Equation 1 can be rewritten as: x + y = -7 (multiply by -1)
Equation 2 can be simplified: x - y = 1 (divide by 5)

The slopes of the lines represented by the two equations are different (they are not multiples of each other) which suggests that the lines will intersect at exactly one point. This means the system of equations is independent.

For this case we have a function of the form [tex]y = h (d)[/tex]. Where:

[tex]h (d) = \frac {4} {9} d + 6 \frac {2} {3}[/tex]

Rewriting the mixed number as a fraction:

[tex]h (d) = \frac {4} {9} d + \frac {3 * 6 + 2} {3}\\h (d) = \frac {4} {9} d + \frac {20} {3}[/tex]

Substituting [tex]d = 3[/tex]:

[tex]h (3) = \frac {4} {9} (3) + \frac {20} {3}\\h (3) = \frac {4} {3} + \frac {20} {3}\\h (3) = \frac {24} {3}\\h (3) = 8[/tex]

Option A

Answer:

x² + y² + 4x - 2y + 1 = 0

Step-by-step explanation:

The equation of a circle is given by the general equation;

(x-a)² + (y-b)² = r² ; where (a,b) is the center of the circle and r is the radius.

In this case; the center is (-2,1)

We can get radius using the formula for magnitude; √((x2-x1)² + (y2-y1)²)

Radius = √((-4- (-2))² + (1-1)²)

             = 2

Therefore;

The equation of the circle will be;

(x+2)² + (y-1)² = 2²

(x+2)² + (y-1)² = 4

Expanding the equation;

x² + 4x + 4 + y² -2y + 1 = 4 subtracting 4 from both sides;

x² + 4x + y² - 2y + 4 + 1 -4 = 0

= x² + y² + 4x - 2y + 1 = 0

Answer:

[tex]\large\boxed{x^2+y^2+4x-2y+1=0}[/tex]

Step-by-step explanation:

The standard form of an equation of a circle:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

(h, k) - center

r - radius

The general form of an equation of a circle:

[tex]x^2+y^2+Dx+Ey+F=0[/tex]

We have the center (-2, 1). Substitute to the equation in the standard form:

[tex](x-(-2))^2+(y-1)^2=r^2\\\\(x+2)^2+(y-1)^2=r^2[/tex]

Put thr coordinates of the point (-4, 1) to the equation and calculate a radius:

[tex](-4+2)^2+(1-1)^2=r^2\\\\r^2=(-2)^2+0^2\\\\r^2=4[/tex]

Therefore we have the equation:

[tex](x+2)^2+(y-1)^2=4[/tex]

Convert to the general form.

Answer: .53

Step-by-step explanation: Of Kylies $550, 32% was for a down payment for summer camp. This is calculated with the formula 550 x .32 = $176 down payment.

She used 3/20 for two video games. 3/20 = .15, so the video games cost .15 x $550 = $82.50.

Kylie spent $176 + $82.50 = $258.50.

$550 savings - $258.50 = $291.50 is the amount that she put into her savings account. Expressed as as decimal, it is 291.50/550 = .53, so she put .53 of her babysitting money into her college savings account.

The constant of variation in a direct variation is found by dividing the y-coordinate by the x-coordinate. Using this constant, we can determine the y-value of a point given the x-value. In this case, n = 5.

In a direct variation, the ratio of the two variables is constant. This means that the product of the two corresponding coordinates of any two points is always the same.

Given a point (4,20), we can find the constant of variation by dividing the y-coordinate by the x-coordinate, which yields 20/4 = 5. So, the constant of variation (k) is 5.

For the point (1, n), the product of the two coordinates should also yield the same constant of variation. Therefore, 1 * n = 5. Solving for n, we find that n = 5.

Answer:

47.1 cm

Step-by-step explanation:

For this problem, I'll use an approximation of [tex]\pi \approx 3.14[/tex], which is good enough for the level of accuracy we need. The definition of π itself is given by the equation

[tex]\pi =\frac{c}{d}[/tex]

where c is the circumference of a circle and d is its diameter. If we want to find the circumference, we can simply multiply both sides of that equation by d to get the formula

[tex]c=\pi d\approx3.14d[/tex]

Here, we're given d = 15 cm, so plugging that in, we find our circumference to be

[tex]c\approx3.14(15)=47.1[/tex]

So the circumference of this circle is approximately 47.1 cm.

The mean of the students' data set is approximately 8.56 hours of sleep per night, while the mean of the teachers' data set is approximately 6.7 hours of sleep per night. This suggests that, on average, students get more sleep than teachers.

To find the mean of a data set, you need to add up all the values and then divide the sum by the total number of values. Let's start by finding the mean of the students' data set. Summing up the values: 7 + 6 + 8 + 9 + 8 + 9 + 10 + 10 + 10 = 77. Since there are 9 values in the data set, we can calculate the mean by dividing the sum by 9: 77 / 9 = 8.56 (rounded to two decimal places). Therefore, the mean of the students' data set is approximately 8.56 hours of sleep per night.

Next, let's find the mean of the teachers' data set. Summing up the values: 6 + 6 + 4 + 5 + 7 + 8 + 7 + 8 + 8 + 8 = 67. Since there are 10 values in the data set, we can calculate the mean by dividing the sum by 10: 67 / 10 = 6.7 (rounded to one decimal place). Therefore, the mean of the teachers' data set is approximately 6.7 hours of sleep per night.

The means tell us the average amount of sleep that students and teachers get each night. The mean of the students' data set (8.56) suggests that, on average, students get more sleep than the mean of the teachers' data set (6.7). This indicates that, based on this survey, students tend to get more sleep than teachers.

Camden's net pay is 76.75% of his gross pay

Alternative:

100%-15.6%-6.2%-1.45%=76.75%

Final answer:

To calculate Camden's net pay, you subtract federal withholding, Social Security, and Medicare deductions from his gross pay based on provided percentages. By applying these calculations to an example, Camden's net pay from a $2,000 gross salary over two weeks would be $1,535, after deductions totaling $465.

Explanation:

The calculation of Camden's net pay involves subtracting federal withholding, Social Security, and Medicare deductions from his gross pay. Assuming Camden's gross pay is a certain amount, we'll illustrate how to find the net pay. Let's not forget to account for the percentages provided for each deduction category: 15.6% for federal withholding, 6.2% for Social Security, and 1.45% for Medicare.

Calculate Federal Withholding: Gross Pay * 15.6%.

Calculate Social Security Deduction: Gross Pay * 6.2%.

Calculate Medicare Deduction: Gross Pay * 1.45%.

Add all deductions together: Federal Withholding + Social Security + Medicare.

Subtract the total deductions from the Gross Pay to get the Net Pay.

For example, if Camden's gross pay is $2,000 for two weeks, his deductions would be:

Federal Withholding: $2,000 * 15.6% = $312

Social Security: $2,000 * 6.2% = $124

Medicare: $2,000 * 1.45% = $29

Total Deductions: $312 + $124 + $29 = $465

Net Pay: $2,000 - $465 = $1,535

After that we have -4x which is actually -4/1 which means +1 for the x-axis and -4 on the y-axis!

Which determines our new point to be on (1, -6)

And you just make the lines now or to make it even easier flip (1, -6) to (-1, 6)

Final answer:

To find the distance between the points (6, -3) and (6, 5), calculate the absolute value of the difference between the y-coordinates, resulting in a distance of 8 units.

Explanation:

The distance between the points (6, −3) and (6, 5) can be found using the distance formula, which is derived from the Pythagorean Theorem. In this particular case, since the x-coordinates of both points are the same, the distance is simply the absolute value of the difference in the y-coordinates.

To calculate the distance (d):
d = |y2 − y1|
d = |5 − (−3)|
d = |5 + 3|
d = |8|
d = 8

Therefore, the distance between the points (6, −3) and (6, 5) is 8 units.
