Answer:
[tex]y+6=\frac{-8}{7} (x-7)[/tex]
Step-by-step explanation:
To find the slope of the equation use [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
So, [tex]\frac{-6-2}{7-0}[/tex] = [tex]\frac{-8}{7}[/tex]. Now we can use our slope and any of the two points to write in point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex]. Using the point (7,-6), the formula will give [tex]y+6=\frac{-8}{7} (x-7)[/tex].
To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.

Three roots of the polynomial equation x^4 - 4x^3 - 2x^2 + 12x + 9 = 0 are 3, -1, and -1. Explain why the forth root must be a real number. Find the forth root.
Hello,
This polynomial function has maximum 4 roots as the degree is 4
and their coefficients are all reals so if one root is a complex number, its conjugate is a root too.
As we know already 3 roots and none of them is a complex number, the fourth one is a real number
And their product is 9 = 3 * 1 * (-1) * (-3) as
[tex](x-x_1)(x-x_2)(x-x_3)(x-x_4)=x^4+...+x_1x_2x_3x_4[/tex]
(The constant term is 9, the product of the roots)
so the last root is -3
Thanks
An internal census of the salaries of animals employed by United Pets Inc. shows that the median salary for dogs is considerably lower than the median salary for cats. Further investigation shows that the median dog salary is higher than the median cat salary in every department (Accounting, Finance, Marketing, etc.) of the company. Which of the following is the most satisfactory explanation for this apparent contradiction?
a. The study is based on a small sample size, so the results are heavily affected by random sampling error.
b. Different departments tend to pay different salaries, and dogs are more likely than cats to work in higher-paying departments.
c. Different departments tend to pay different salaries, and dogs are more likely than cats to work in lower-paying departments.
d. There are many more cats than dogs employed by this company.
e. There are many more dogs than cats employed by this company.
f. There is a very small fraction of cats in each department that earns extremely high salaries compared to everyone else (for example, the chief executives).
Answer:
c. Different departments tend to pay different salaries, and dogs are more likely than cats to work in lower-paying departments.
Explanation:
The only explanation for difference in median results is that dogs take up jobs in both higher paying departments and lower paying departments while cats take up jobs in only higher paying departments only. In other words the median results for dogs when compared in general would be higher than that of the cats

Y=-4 when x=32, find x when y=-0.375
Answer:
x = 3
Step-by-step explanation:
This can be set up as a proportion.
[tex]\frac{32}{-4} = \frac{x}{-0.375} \\[/tex]
Then, cross multiply -4x = -12. (The -12 came from multiplying 32 and -0.375). Divide both sides by -4 to get x = 3.
4.) Laura works in a furniture store. She earns $160 a week plus 6% of all sales over
$2,000. One week in January, Laura's total sales were $9,400. What were Laura's
earnings for that week?
Answer:
$724
Step-by-step explanation:
We know she makes the 6% of the 9,400, so we need to find how much that is.
To do this we calculate the following equation: 9,400 * 0.06
When we solve this, we get 564. From there we add her weekly salary (160) and get 724.
Answer:
$724
Step-by-step explanation:
You can do this one of two ways. The first way is to set up an equation.
160+0.06(9400)
160+564
724
Or you can use proportions.
[tex]\frac{x}{9400}[/tex] = [tex]\frac{6}{100}[/tex]
Cross multiply.
100x=56400
Divide by 100 on both sides.
x=564
Add 160.
564+160=724.

A company handles an apartment building with 50 units. Experience has shown that if the rent for each of the units is $760 per month, all of the units will be filled, but 1 unit will become vacant for each $20 increase in this monthly rate. If the monthly cost of maintaining the apartment building is $12 per rented unit, what rent should be charged per month to maximize the profit?

Consider rhombus G H I J with diagonals IG and HJ
Answer:
Option (1)
Step-by-step explanation:
Properties of the angles of a rhombus:
1). Diagonals are perpendicular.
2). Opposite angles are equal in measure.
3). Diagonals bisect the angles at the vertices.
Given: m∠GJH = 18°
In ΔGJH,
m∠GJH + m∠GHJ + m∠JGH = 180°
m∠GJH + m∠GJH + m∠JGH = 180° [Since, ∠GJH ≅ ∠GHJ diagonals bisect the opposite angles and opposite angles are equal in measure]
2m∠GJH + m∠JGH = 180°
2(18)° + m∠JGH = 180°
m∠JGH = 180° - 36°
= 144°
Since, opposite angles of a rhombus are equal,
m∠JGH = m∠JIH = 144°
Option (1) will be the answer.
Solve the following equation - 2(x-8)=18-3(5x+6)
Answer:
-2(x-8)=18-3(5x+6)
-2x+16=18-15x-18
-2x+15x=18-18+16
13x=16
X=16/13
Answer:
[tex]x=-\frac{16}{13}[/tex]
Step-by-step explanation:
[tex]-2(x-8)=18-3(5x+6)[/tex]
Start by distributing [tex]-2[/tex] into [tex](x-8)[/tex], and [tex]-3[/tex] into [tex](5x+6)[/tex]:
[tex]-2x+16=18-15x-18[/tex]
Combine like terms:
[tex]-2x+16=-15x[/tex]
Subtract [tex]16[/tex] from both sides of the equation:
[tex]-2x=-15x-16[/tex]
Add [tex]15x[/tex] to both sides of the equation:
[tex]-13x=16[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-13[/tex]:
[tex]x=-\frac{16}{13}[/tex]

Given that 5W = 2P + 3R find the value of P when W = 4 and R = −4
Answer:
P = 16
Step-by-step explanation:
Given
5W = 2P + 3R ← substitute W = 4 and R = - 4 into the equation
5(4) = 2P + 3(- 4), that is
20 = 2P - 12 ( add 12 to both sides )
32 = 2P ( divide both sides by 2 )
16 = P

Calculate the peak hour volume for six-15 minute periods with the following volumes: 125, 130, 135, 140, 145, 155
Answer:
The peak hour volume is 620
Step-by-step explanation:
Here, we want to calculate the peak hour volume
To calculate the peak hour volume, we need some information
Firstly we need to know that a period of 15 minutes refer to 1/4 of an hour
So, the given volume needs to be multiplied by 4 to get the peak hour value
Now back to the values given, we need the highest of them all
As regards the question, the highest of them all is 155
So the peak hour volume here would be 155 * 4 = 620

Step-by-step explanation:
angle AEB = 180° - (25°+25°) (isosceles triangle)
= 180° - 50°
= 130°
angle AEB = angle CED = 130° (vertically opp angle)
angle ECD = 25° (alternate angle)
angle CDE = 180° - (25°+130°) (angle sum of a triangle)
= 180° - 155°
= 25°
