Please help a girl out. My best friend is having trouble with this and I can't figure it out either. Thank you!

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Step-by-step explanation:

If the circle is dilated by a factor 4 then the radius becomes \(4\sqrt{2}\) units.

Area is the quantity that shows the extent of surface covered. Area of circle is π\(r^{2}\). where r is radius.

Before dilation the radius will be \(\sqrt{(0-0)^{2} +(4-0)^{2} }\)

=\(\sqrt{16}\)

=4 units.

If the circle is dilated by factor of 4 then the area will increase byπ \((4)^{2}\)=16π

Area before dilation =16π .

Area after dilation=16π+16π=32π.

π\(r^{2}\)=32π

\(r^{2}\)=32

r=\(4\sqrt{2}\)units.

Hence the distance equal to radius is 4\(\sqrt{2}\) units.

Step-by-step explanation:

For Big Circle

Radius (R) = 11yd

We know Area of a circle,

(A1) = πr²

(A1) = 3.14×11²

(A1) = 379.94yd²

For Small Circle

Radius (R) = 6yd

We know Area of a circle,

(A2) = πr²

(A2) = 3.14×6²

(A2) = 113.04yd²

Now,

Area of the shaded region = A1 - A2

= 379.94yd²-113.04yd²

= 266yd²

Therefore, Area of the shaded region is 266yd²

Answer: The answer to your question is

           A) True.

Answer:

true

Step-by-step explanation:

Sure, I can help you with that.

**Part A: Calculate the measures of center.**

The measures of center are the mean, median, and mode.

* **Mean:** The mean is calculated by adding all the values in the data set and dividing by the number of values. For the Sky View School data set, the mean is 5.8. For the South Lake School data set, the mean is 5.4.

* **Median:** The median is the middle value in the data set when the values are arranged in increasing order. For the Sky View School data set, the median is 6. For the South Lake School data set, the median is 5.5.

* **Mode:** The mode is the most frequent value in the data set. For the Sky View School data set, the mode is 5. For the South Lake School data set, the mode is 5.

**Part B: Calculate the measures of variability.**

The measures of variability are the range, standard deviation, and variance.

* **Range:** The range is the difference between the largest and smallest values in the data set. For the Sky View School data set, the range is 8. For the South Lake School data set, the range is 8.

* **Standard deviation:** The standard deviation is a measure of how spread out the data is. The larger the standard deviation, the more spread out the data is. For the Sky View School data set, the standard deviation is 1.7. For the South Lake School data set, the standard deviation is 1.5.

* **Variance:** The variance is the square of the standard deviation. For the Sky View School data set, the variance is 2.89. For the South Lake School data set, the variance is 2.25.

**Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning.**

If you are interested in a smaller class size, then the South Lake School is a better choice. The average class size at the South Lake School is 5.4, while the average class size at the Sky View School is 5.8. Additionally, the median class size at the South Lake School is 5.5, while the median class size at the Sky View School is 6. This means that half of the classes at the South Lake School have 5 or fewer students, while half of the classes at the Sky View School have 6 or more students.

Step-by-step explanation:

Answer:

A movie is $2.5

A video game is $6

Step-by-step explanation:

We are given that Ann had rented 2 movies and 5 video games for a total of $35.

We also know that she also rented 8 movies and 3 video games for a total of $38.

We want to know how much a movie costs, and how much a video game costs.

If a movie costs x dollars, then a video game costs y dollars.

This means that costwise, 2 movies will cost 2x, and 5 video games will be 5y.

8 movies will cost 8x, and 3 video games will cost 3y.

So, we will have two equations:

2x + 5y = 35

8x + 3y = 38

We now have this system of equations, which we can solve.

Let's solve this by elimination.

To eliminate, we need to clear one of the variables, and solve for the other one.

To do this, we need to make sure that one variable has the same coefficient with opposite signs (e.g. -3x and 3x). We might need to multiply one equation by a number in order to achieve this.

We can multiply 2x + 5y = 35 by -4.

-4(2x + 5y) = -4(35)

-8x - 20y = -140

We can rewrite the equations:

-8x - 20y = -140

8x + 3y = 38

They can be added together. The result will be:

-17y = -102

Divide both sides by 017.

y = 6

We found y, but now we need to find x.

We can substitute 6 as y into 2x + 5y = 35 or 8x + 3y = 38 to find x.

Taking 2x + 5y = 35 for instance:

2x + 5(6) = 35

2x + 30 = 35

Subtract 30 from both sides.

2x = 5

Divide both sides by 2

x = 2.5

Recall that x = price of a movie, and y = price of a video game.

Therefore, a movie is 2.5 dollars, and a video game is 6 dollars.

9.4868 cm Rounded: 9.5cm

Step-by-step explanation:

V(Volume) = 1/3 x B(Base area) x h

300 = 1/3 x B x 9

10 x 1/3 = 10,3

300/10,3 = 90

B = 90^2

l(length of the base) = \(\sqrt 90\) = 9.4868

Rounded Answer (to the first decimal) = 9.5

To define Payroll tax.

Now, Payroll tax refers to the taxes that are deducted from an employee's wages or salary by their employer.

These taxes are withheld to fund various government programs and services.

Payroll taxes typically include federal, state, and local income taxes, as well as Social Security and Medicare taxes.

The amount of payroll taxes deducted from an employee's paycheck depends on factors such as income level, tax brackets, and the tax rates set by the applicable government authorities.

These taxes are then remitted by the employer to the appropriate tax agencies on behalf of their employees.

They are specifically related to employment income and play a crucial role in funding important government initiatives and social programs.
