Step 02:

Line AB

Slope formula

m = (y2 - y1) / (x2 - x1)

A (2 , 3) x1 = 2 y1 = 3

B (8 , 7) x2 = 8 y2 = 7

[tex]m\text{ = }\frac{7-3}{8-2}=\frac{4}{6}=\frac{2}{3}[/tex]

In an art classroom, 8 students can sit around 1 table, and 48 students can sit around 6 tables. What is the relationship between the number of students to tables? (Do not reduce the ratios to their lowest terms.)

Answers

Answer: 8/1 = 6/48

Step-by-step explanation: um thats the answer bye

The relationship between the number of students to tables or the ratio of students to number of tables is 8 to 1.

According to question,

We have the following information:

In an art classroom, 8 students can sit around 1 table, and 48 students can sit around 6 tables.

Now, we will find the relationship between the number of students and the number of tables or in simple words, ratio.

So, we have:

8 students = 1 table

48 students = 6 tables

It can be rewritten by dividing both the sides by 6 as 8 students to 1 table.

It means that there are 8 students for 1 table.

Hence, the relationship between the number of students to the number of tables is 8 to 1.

Need help with a math word problem for homework. Thank you in advance

Answers

Given:

A client is making a 10-lb bag of trail mix

The chocolates cost $4 per pound and mixed nuts cost $7 per pound

the client has a budget of $6.1 per pound

We will use the variables c and n to represent the number of pounds for chocolates and nuts

So, we have the following system of equations:

[tex]\begin{gathered} c+n=10\rightarrow(1) \\ 4c+7n=6.1\cdot10\rightarrow(2) \end{gathered}[/tex]

Solving the system by substitution method

From equation (1)

[tex]c=10-n\rightarrow(3)[/tex]

substitute with (c) from equation (3) into equation (2)

[tex]\begin{gathered} 4(10-n)+7n=6.1\cdot10 \\ \end{gathered}[/tex]

solve the equation to find (n)

[tex]\begin{gathered} 4\cdot10-4n+7n=6.1\cdot10 \\ -4n+7n=6.1\cdot10-4\cdot10 \\ 3n=21 \\ n=\frac{21}{3}=7 \end{gathered}[/tex]

Substitute with (n) into equation (3) to find (c)

[tex]c=10-7=3[/tex]

so, the answer will be:

The number of pounds of chocolates = c = 3 pounds

The number of pounds of nuts = n = 7 pounds

How do I graph a line with a equation in slope intercept form?An example is y=-3x+3, how do I graph this?

Answers

we have

y=-3x+3

to graph a line we need at least two points

so

Find out the intercepts

y-intercept (value of y when the value of x is zero)

For x=0

y=-3(0)+3

y=3

y-intercept is (0,3)

x-intercept (value of x when the value of y is zero)

For y=0

Assume your salary is $24,000 per year and $50 for each computer you sell. What function represents your total pay for one year? Be sure to indicate any domain restrictions.

Answers

Let x represent the total amount of computers you sell in one year.

Since you get $50 for each computer, then, you would get 50x for x computers.

Additionally, your base salary is $24,000. Then, add 50x and 24,000 to find your total salary in a year.

If f(x) is a function that represents your salary depending on the amount of computers you sell, then:

[tex]f(x)=50x+24000[/tex]

Notice that the amount of computers that you sell cannot be a negative number. Then, you must take into account the following restriction:

Carla has made a list of supplies that she needs to make the entire order. Each arrangement needs a plastic molding. It will cost Carla $3.25 for each plastic molding. She also needs 4 packages of colored netting, which sell for $15.00 each. However, the company she orders from has a special on the netting packages. If you buy 3 packages of netting, you get a package for free. Polyester fabric is another item she will need. She needs 180 square feet of polyester fabric that sells for $5.20 per square yard. Lastly she needs artificial stems. She will need 6 stems per arrangement and they are sold in packs of 10. The cost for one pack of artificial stems is $2.50. if Carla sells each arrangement for $20.00,How much money will Carla make off the order once she subtracts her expenses for the supplies.

Answers

Substract expenses

Carlas expenses are

1. 100 Arrangements

2. Plastic molding PM = 3.25

3. Colored netting CN = 15

4. Four packages netting = 3 packages

5. 180 feet2 ,. 1 yard2=5.20

6. 10 stems = 2.5x10 = $25

7. Arrangement price AP = 20.00

Then substract

20 minus 3.25 = 16.75

16.75 x100= $1675

4. 4 packages nettingx 15 = $60 - $15 = $45

5. Now

In 180 feet2 ,there are 60 yards2

then polyester price is 60x5.2= $312

6. She needs 100x6= 600 stems

600/10 = 60 packs

60 packs x 2.50= $150

Then answer is

Carla's money = 1675 - 45 - 312 - 150 = $1168 dollars

As shown at the graph, we need to find x and y

The angles (x+1) and (2y+1) are vertical

so, x + 1 = 2y + 1

so,

x = 2y eq.(1)

And the sum of the angles (x+1) , (3x + 4y) and (71 - 3y) are 180

So,

(x+1) + (3x + 4y) + (71-3y) = 180

x + 1 + 3x + 4y + 71 - 3y = 180

4x + y = 180 - 1 - 71

4x + y = 108

Substitute with x from eq (1) with 2y

4 * 2y + y = 108

8y + y = 108

9y = 108

y = 108/9 = 12

x = 2y = 2 * 12 = 24

So, x = 24 and y = 12

(x). Leonhard Euler invented functional notation in 1734. Some commonly used functions are represented with a symbol made up of many letters (usually two or three, generally an abbreviation of their name). In this scenario, a roman font is typically used, such as "sine" for the sine function, rather than an italic font for single-letter symbols. A function is also known as a map or a mapping, however some writers distinguish between "map" and "function."

The function can be written as

3x+4y-7 = 0

or, y = (-3/4)x + 7/4

so, slope = -3/4

and other function is

kx+12y+3 = 0

or, y = (-k/12)x - 1/4

so, slope = -x/12

Given the lines are parallel, so slopes are equal

[tex]\begin{gathered} m_2=\frac{4}{5} \\ m_1=-\frac{1}{\frac{4}{5}_{}} \\ m_1=-\frac{\frac{1}{1}}{\frac{4}{5}_{}} \\ m_1=-\frac{1\cdot5}{1\cdot4} \\ $$\boldsymbol{m}_{\boldsymbol{1}}\boldsymbol{=-\frac{5}{4}}$$ \end{gathered}[/tex]Step 2

Since we already have a point on the line and its slope, then we can use the point-slope formula:

[tex]\begin{gathered} y-y_1=m(x-x_1)\Rightarrow\text{ Point-slope formula} \\ \text{ Where } \\ m\text{ is the slope and} \\ (x_1,y_1)\text{ is a point through which the line passes} \end{gathered}[/tex]

Then, we have:

[tex]\begin{gathered} (x_1,y_1)=(6,3) \\ m=-\frac{5}{4} \\ y-3=-\frac{5}{4}(x-6) \\ \text{ Apply the distributive property} \\ y-3=-\frac{5}{4}\cdot x-\frac{5}{4}\cdot-6 \\ y-3=-\frac{5}{4}x+\frac{5}{4}\cdot6 \\ y-3=-\frac{5}{4}x+\frac{30}{4} \\ \text{ Add 3 from both sides of the equation} \\ y-3+3=-\frac{5}{4}x+\frac{30}{4}+3 \\ y=-\frac{5}{4}x+\frac{30}{4}+\frac{12}{4} \\ y=-\frac{5}{4}x+\frac{30+12}{4} \\ y=-\frac{5}{4}x+\frac{42}{4} \\ \text{ Simplify} \\ y=-\frac{5}{4}x+\frac{21\cdot2}{2\cdot2} \\ y=-\frac{5}{4}x+\frac{21}{2} \end{gathered}[/tex]Step 3

Therefore, the equation of the line that passes through the point (6,3) that is perpendicular to the line 4x - 5y = -10 is

[tex]$$\boldsymbol{y=-\frac{5}{4}x+\frac{21}{2}}$$[/tex]

Consider the following system of equations.ſ x - 4y = -34x - 2y = -12Step 2 of 2: Determine if the point (3, 1) lies on both of the lines in the system of equations by substituting theordered pair into both equations.

Answers

Given:

x - 4y = -3

4x - 2y = -12

To determine if the point (3, 1) lies on both of the lines in the system of equations:

Substitute (3, 1) in the first equation, we get

3 - 4(1) = -3

3 - 4 =-3

-1 = -3

But,

[tex]-1\ne-3[/tex]

Substitute (3, 1) in the second equation, we get

4(3) - 2(1) = -12

12 - 2 = -12

10 = -12

But,

[tex]10\ne-12[/tex]

Hence, the answer is, No.

The point (3, 1) does not lie on both of the lines in the system of equations.

An elliptical-shaped path surrounds a garden, modeled by quantity x minus 20 end quantity squared over 169 plus quantity y minus 18 end quantity squared over 289 equals 1 comma where all measurements are in feet. What is the maximum distance between any two persons on the path, and what key feature does this represent?

Answers

In general, the equation of an ellipse centered at (h,k) and axis equal to a and b, and parallel to the y-axis is

[tex]\frac{(x-h)^2}{b^2}+\frac{(y-k)^2}{a^2}=1,a>b[/tex]

And the maximum distance between two points on the ellipse is equal to the length of the major axis; in our case,

[tex]\begin{gathered} a^2=289,b^2=169 \\ \Rightarrow a=17,b=13 \end{gathered}[/tex]

Therefore, the answer is 17 feet, the major axis.

From the diagram provided, we have a right angled triangle with the hypotenuse (side facing the right angle) given as 55, while one of the other two sides is given as 44.

We shall apply the pythagoras' theorem as follows;

[tex]c^2=a^2+b^2[/tex]

Where,

c = hypotenuse,

a and b = the other sides.

Therefore, we'll now have;

[tex]\begin{gathered} c^2=a^2+b^2 \\ 55^2=44^2+c^2 \\ 3025=1936+c^2 \end{gathered}[/tex]

Next step, we'll subtract 1936 from both sides of the equation;

[tex]\begin{gathered} 3025-1936=1936-1936+c^2 \\ 1089=c^2 \end{gathered}[/tex]

Add the square root sign to both sides of the equation;

[tex]\begin{gathered} \sqrt[]{1089}=\sqrt[]{c^2} \\ 33=c \end{gathered}[/tex]

ANSWER

Therefore, the correct answer is option C, that is 33 inches.
