Answer:

The parallel line has slope [tex]\frac{20}{7}[/tex]

The perpendicular line has slope [tex]-\frac{7}{20}[/tex]

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

[tex]y = mx + b[/tex]

In which m is the slope.

Parallel lines:

Parallel lines have the same slope.

Perpendicular lines:

If two lines are perpendicular, the multiplication of their slopes is -1.

In this question:

We have the following line:

[tex]7y = 20(x-3)[/tex]

Placing it in the general format

[tex]7y = 20x - 60[/tex]

[tex]y = \frac{20x}{7} - \frac{60}{7}[/tex]

So this line has slope [tex]\frac{20}{7}[/tex]

Parallel line:

Same slope, so the parallel line has slope [tex]\frac{20}{7}[/tex]

Perpendicular line:

Multiplication of the slopes is -1. So

[tex]\frac{20m}{7} = -1[/tex]

[tex]20m = -7[/tex]

[tex]m = -\frac{7}{20}[/tex]

The perpendicular line has slope [tex]-\frac{7}{20}[/tex]

Answer:

[tex]-\frac{7}{24}[/tex]

Step-by-step explanation:

When subtracting a negative, it turns into a positive, so:

[tex]\frac{1}{8} -\frac{5}{12}[/tex]

Now find a common denominator:

[tex]\frac{3}{24} -\frac{10}{24}[/tex]

[tex]-\frac{7}{24}[/tex]

Answer:

254 4/7 or 254.34 ft² (it depends on which method you use.)

Step-by-step explanation:

To find the area of a circle, the formula is πr².

I'll use both 22/7 and 3.14 as pi, so I'll end up with two different answers. Just choose the more reliable one.

22/7 version:

22/7 * 9^2

22/7 * 81/1

1782/7

254 4/7 ft²

3.14 version:

3.14 * 9^2

3.14 * 81

314 - (3.14 * 19)

314 - 62.8 + 3.14

251.2 + 3.14

254.34 ft²

As I said, I ended up with two different answers. You also had said not to round my answer, so the 22/7 version has a mixed number.

Explanation: Decimals represent fractions

with denominators of 10, 100, 1000, and so on.

Therefore, in order to write 3/5 as a decimal, we must first find a

fraction equivalent to 3/5 with a denominator of 10.

So we multiply the numerator and denominator

of 3/5 by 2 to get the equivalent fraction 6/10.

Since 6/10 is written as the decimal 0.6,

3/5 must be equivalent to 0.6.

Answer:

x = 6   y = -9   (I took a complicated route so if my explanation doesn't make sense It's fine)

Step-by-step explanation:

DAY = FUN

F = (7x+2y) = 24

If DAY = FUN then D = F making (7x + 2y) = 24

This means A = U so you have to find U with 24+126=150

A triangle is 180 degrees so you would do 180-150=30

U = 30

This also makes (8x+2y) = 30

8x + 2y = 30

-8x           -8x

2y = 30 - 8x

Divide everything by 2

y = 15 - 4x

Doing this you can take 7x + 2y = 24 and plug in 7x + 2(15 - 4x) = 24

Multiply it 7x + 30 - 8x = 24

Add like terms -x + 30 = 24

Subtract 30      -x = -6

Divide by -1       x = 6

Now take one of the equations and plug it in 7(6) + 2y = 24

Multiply 42 + 2y = 24

Subtract 2y = -18

Divide by 2    y = -9

first three natural numbers

First, three natural numbers notation describes {1, 2, 3}.

In mathematics, set notation is essentially a list of numbers, things, or results. Curly brackets, often known as braces, are used for set notation. The items included between brackets are referred to as elements of a set and are not required to be in any particular order.

Given, a set  {1, 2, 3}

Since a set notation used to represent the elements of a set is the curly brackets { }. An example of a set is A = {a, b, c, d}. Here the set is represented with a capital letter, and its elements are denoted by small letters.

These given number best fit in the category of natural numbers.

Therefore, First, the notation for three natural numbers shows  {1, 2, 3}.

Simplified form of: [tex](4x^2+x-6)(-6x-1)[/tex] is [tex]\mathbf{-24x^3-10x^2+35x+6}[/tex]

Step-by-step explanation:

We need to write the simplified answer of: [tex](4x^2+x-6)(-6x-1)[/tex]

We are multiplying both terms.

First -6x is multiplied with [tex](4x^2+x-6)[/tex] and then -1 is multiplied with [tex](4x^2+x-6)[/tex]

Looking at the table, we now just have to add the like terms to find the result.

[tex]-6x(4x^2+x-6)-1(4x^2+x-6)\\=-24x^3-6x^2+36x-4x^2-x+6\\Now\:combining\:like\:terms:\\=-24x^3-6x^2-4x^2+36x-x+6\\=-24x^3-10x^2+35x+6[/tex]

So, simplified form of: [tex](4x^2+x-6)(-6x-1)[/tex] is [tex]\mathbf{-24x^3-10x^2+35x+6}[/tex]

Answer:

y= –x + 1

Step-by-step explanation:

to write an equation in slope-intercept form, y = mx + b, calculate the slope, m, as rise/ run

The difference in y-values, rise, is –2

The difference between x-values is 2

–2/2 = m, the slope is –1

substitute for m, and it use any set of given y and x values in the equation to solve for b.

y= mx +b

–2 = –1(3) + b. Add 3 to both sides.

3 –2 = 3 –3 + b

1 = b

use the calculated m and b to write the equation with y and x

y = –x + 1

Answer:

They saved $3000 in 2014

Step-by-step explanation:

Given

[tex]Savings (2013) = \$12500[/tex]

[tex]Total (2014) = \$15500[/tex]

Required

Determine the savings in 2014

This is calculated by subtracting the savings in 2013 from the total savings.

i.e.

[tex]Savings(2014) = Total(2014) - Savings(2013)[/tex]

This gives:

[tex]Savings(2014) = \$15500 - \$12500[/tex]

[tex]Savings(2014) = \$3000[/tex]

Hence, they saved $3000 in 2014

Answer:

The expected value for the game is of -$4.5

Step-by-step explanation:

The expected value of the game is given by each scenario multiplied by its probability.

Scenario 1: Player wins

1 correct number from a set of 1000, so probability of 1/1000.

In this case, the player spent $5, but earns $500, so a net of 500 - 5 = $495

Scenario 2: Player loses

Probability of 999/1000.

In this case, the player loses $5.

So, the expected value for the game is:

[tex]E = \frac{495*1}{1000} - \frac{5*999}{1000} = -4.5[/tex]

The expected value for the game is of -$4.5

The equation which reveals the dimensions that will create the maximum area of the prop section is;

[tex]A = - (x-20)^2 + 400[/tex]

Option D is true.

Here,

We have to find, The equation which reveals the dimensions that will create the maximum area of the prop section.

What is Dimension?

The measure of the size or distance of an object or region or space in one direction is called Dimension.

Now,

The area of the sectioned off space, A, is modeled by this equation;

[tex]A = -x^{2} + 40x[/tex]

Where,  x is the width of the prop section.

Hence,

[tex]A = -x^{2} + 40x\\\\A = - (x^{2} -40x)\\\\A = - ((x - 20)^2 - 20^2)\\\\A = - ((x-20)^2 - 400)\\\\A = - (x-20)^2 + 400[/tex]

Clearly, We can say that;

A ≤ 400

So,

The equation which reveals the dimensions that will create the maximum area of the prop section is;

[tex]A = - (x-20)^2 + 400[/tex]

Option D is true.
