We can find the two linear equations by using the point-slope form of a line: y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line.

For the first equation:

Using the first point (-2, 8), we have m = (y2 - y1) / (x2 - x1) = (-3 - 8) / (-2 - (-2)) = -11/0, which is undefined. This means the first line is a vertical line.

The equation can then be written as x = -2, since the x-coordinate is constant.

For the second equation:

Using the second point (-1, 4), we have m = (y2 - y1) / (x2 - x1) = (-2 - 4) / (-1 - (-2)) = -2.

The equation can then be written as y - 4 = -2(x + 1), or y = -2x - 2.

Thus, the system of linear equations is:

x = -2

y = -2x - 2

Written in standard form:

x + 0y = -2

-2x + y = -2

An amount of $ 13,200 has a total comission of 856.

Herein we find the case of the calculation of a comission for an amount of money, where an interest rate of six percent is applied for first $ 10.000 and an interest rate of eight percent is applied for the excedent above $ 10.000. The total comission is determined by following mathematical equation:

C = 10,000 · (6 / 100) + (13,200 - 10,000) · (8 / 100)

C = 856

The graduate must pay a total comission of $ 856 for an amount of $ 13,200.

Answer:

Step-by-step explanation:

Since the base x is consistent with all terms of this complex fraction, all you need to do is add the two exponents found in the numerator and from that, subtract the exponent in the denominator.

This gives us x^(3/5) divided by x^(4/5), which is x^(-1/5). This gives 1/x^(1/5), which is 1 divided by the fifth root of x.

Justice had the rented car for 22 days, when the rent per day is $20 with $50 deposit.

Rent is a periodic payment made by a tenant to a landlord in exchange for the use of land, building, apartment, office, or other property. A payment or series of payments made by a lessee to an owner in exchange for the use of machinery, equipment, etc. 

According to the information in the question:

Deposit = $50

Rent cost per day for the car = $20

Total amount that Justice has to pay = $490

∴ Total number of days that Justice kept the car = (490 - 50)/20

                                                                                 = 440/20

                                                                                 = 22 days

The number of days did he have the car are 22.5 days.

a set monthly fee that you pay to utilise someone else's space, including their home, car, television, etc. Because my room is larger than the other renters', I pay a higher rent or more rent.

Justice rented a car for a deposit of $50 and a daily rate of $20. When he returned the car, he owed $490.

To find out how many days he had the car, we can set up an equation:

$50 + (number of days x $20) = $490.

Solving for the number of days: number of days = ($490-$50)/$20 = 22.5 days.

So Justice had the car for approximately 22.5 days.

Using trigonometry formulas, the value of tan(x-y) = -16/63

In the field of mathematics known as trigonometry, correlations between angles and length ratios are studied. Trigonometry has a wide variety of identities. In order to simplify an expression, identify a more practical version of an expression, or solve an equation, trigonometric identities are frequently employed to rewrite trigonometrical expressions.

Given

cot y = 4/3

1/tan y = 4/3

Cross multiply

tan y = 3/4

Also since csc x = 13/5

1/sin x = 13/5

sin x = 5/13

Since sin x = opp/hyp

opp = 5

hyp = 13

Get the adjacent

hyp² = opp²+adj²

13² = 5²+adj²

adj² = 13² - 5²

adj² = 169 - 25

adj² = 144

adj = 12

cos x = adj/hyp

cos x = 12/13

tan x = sin x/ cos x

tan x = (5/13)/(12/13)

tan x = 5/13 * 13/12

tan x = 5/12

tan(x-y) = tan x - tan y/1 + tan x * tan y

tan(x-y) = (5/12 - 3/4) / 1 + (5/12) (3/4)

tan(x-y) = (5-9/12) / 1 + 5/16

tan(x-y) = -4/12/(21/16)

tan(x-y) = -1/3 * 16/21

tan(x-y) = -16/63

the value of tan(x-y) is -16/63

r = red tiles

b = blue tiles

b = r + 12 , whatever "r" is, "b" is 12 more than that

[tex]\stackrel{red}{3}~~ : ~~\stackrel{blue}{5}\qquad \implies \cfrac{r}{b}=\cfrac{3}{5}\implies \cfrac{r}{r+12}=\cfrac{3}{5}\implies 5r=3r+36 \\\\\\ 2r=36\implies r=\cfrac{36}{2}\implies r=18[/tex]

Answer:

18

Step-by-step explanation:

Because there are 12 more blue tiles than red, that means that we can write the equation 3x + 12 = 5x. By simplifying, the equation is boiled down to 12=2x. By dividing, we see that x=6. This means that we can multiply 3 by 6 to get 18 red tiles. To check our answer, we just multiply 6 by 5 to get 30, and the ratio 18:30 is equivalent to 3:5. Also, 30-18=12, so this must be correct.

  ㏒₅₄168 = (1+ab)/(8a-5ab)

Step-by-step explanation:

You want ㏒₅₄168 written in terms of a and b, where ...

The rules of logarithms are relevant here:

  [tex]\log_b(a)=\dfrac{\log(a)}{\log(b)}\\\\\log(ab)=\log(a)+\log(b)[/tex]

In order to simplify the writing in what follows, we want to define ...

Now, we can write the equations ...

  a = log(12)/log(7) = (2p+q)/r . . . . . . . . . [eq1]

  b = log(24)/log(12) = (3p+q)/(2p+q) . . . [eq2]

Using these, we can solve for p and q:

  2p +q = ar . . . . . . . . . . . . . [eq3], from [eq1]

  (3 -2b)p +(1 -b)q = 0 . . . . . [eq4] from [eq2]

Using your favorite solution method for linear equations, you find ...

  p = ar(1 -b)/(2(1 -b) -(3 -2b)) = ar(1 -b)/(2 -2b -3 +2b) = ar(b -1)

  q = (-ar(3 -2b)/(-1) = ar(3 -2b)

Substituting these expressions into ...

  [tex]\log_{54}{168}=\dfrac{\log{(2^3\cdot3\cdot7)}}{\log{(2\cdot3^3)}}=\dfrac{3p+q+r}{p+3q}\\\\=\dfrac{3ar(b-1)+ar(3-2b)+r}{ar(b-1)+3ar(3-2b)}=\dfrac{3ab-3a+3a-2ab+1}{ab-a+9a-6ab}\\\\=\boxed{\log_{54}{168}=\dfrac{1+ab}{8a-5ab}}[/tex]

The age that she must work till she is qualified to receive Social Security benefits when she retires is: 56 years

Social Security benefits provide partial replacement income for retired beneficiaries and disabled persons, as well as their spouses, children and survivors.

To be eligible for Social Security benefits, you must be enrolled in the Social Security program and accumulate 40 credits while employed.

Benefits are based on your income history, year of birth, and age at which you began applying for Social Security.

If your spouse is unemployed or has not reached the required number of credits, you can receive benefits according to your spouse's work performance.

Benefits may likely be taxed based on the specific income and tax return status.

She will be required to earn a total of 40 credits in order to qualify to be able to receive social security benefits, due to the fact that she earns the maximum number of 4 credits per year, she therefore has to work for at least a minimum of ten years or until at least she is 56.

Answer:

25 copies rented

Step-by-step explanation:

r = r1 - 5t, t is time in weeks, r is the number of copies rented, r1 how many people were renting at the start

we know on the 6 weeks passed and 4 copies were rented

4 = r1 - 5(6)

4 = r1 - 30; add 30 on both sides

34 = r1

r = 34 - 5t now plug t = 2 in for this function

r = 34 - 5(2)

r = 35 - 10

r = 25 copies rented

Answer:

Step-by-step explanation:

Finding an equation of a line can be condensed into 2 easy steps.  Step one is to establish the basic form of the equation, including it's slope.  

1)  Lets use y=mx + b as the basic form, where m is the slope and b is the y-intercept (the value of y when x is zero).  We are told the line is parallel to y = 3x - 1, which is a line with a slope (m) of 3.  Parallel lines have the same slope, so our kline will also have a slope of 3, bringing us to:

   y = 3x + b.

2)  The second step is finding the value of b.  We are told the line must go through point (1,5), so we need a value of b that will shift the line to (1,5).  Easy:  just enter this point in the equation we have so far:  y = 3x + b:

y = 3x + b

5 = 3*(1) + b for point (1,5)

b = 2

The equation becomes y = 3x + 2

See the attached graph.  [Extra credit]

The lines are parallel, and the y-intercept for the second line (b) is (0,2).

To completely understand all of the facets of quantitative data, statistical analysis—the discipline of obtaining, analysing, and presenting enormous volumes of data to uncover patterns and trends—is used. This calls for quantitative analysis employing a wide variety of data.

Categorical data is data that may be arranged into groups or categories using names or labels.
