Answer:

A. 1 (or 1x or x in the equation)

B. 1 (or (0, 1) on the graph)

C. y=x+1

Step-by-step explanation:

The formula for slope is rise over run, or rise/run. This means that you take the amount a line rises (or decreases) between 2 points. The run is the distance on the x-axis (___ looking line) that separate the two points. The y-intercept is going to be the point that is on the y-axis, the vertical line (| looking line). To find the equation, you take the slope, multiply that to x, and add the y-value of the y-intercept.

A rhombus has sides of length x + 6 inches and a perimeter of 49 inches. Which equation represents this situation?

Answers

Answer:

Step-by-step explanation:

The equation representing this situation is 4( x + 6 ) = 49.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a rhombus has sides of length x + 6 inches and a perimeter of 49 inches.

The equation can be written as,

4 ( x + 6 ) = 49

The perimeter is given as,

4 x side = perimeter

4 x ( x + 6 ) = 49

4 ( x + 6) = 49

2x² + 15x + 27

Step-by-step explanation:

(2x + 9)(x+3)

2x² + 6x + 9x+ 27

2x² + 15x + 27

Answer:

2x² + 15x +27

Step-by-step explanation:

Using FOIL:

⇒ 2x * x = 2x²

⇒ 2x * 3 = 6x

⇒ 9 * x = 9x

⇒ 9 * 3 = 27

It would add up to; 2x² + (6x + 9x) +27 and simplifying the parenthesis would simplify to 2x² + 15x +27.

I'm sorry I have no clue what this is. What grade are you in? I'm in seventh and I have never learned anything like this lol.

Step-by-step explanation:

3)first you count the sides
There are 8 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(8-2)*180
=6*180=1080

To find the measure of one interior angles divide the answer by the number of sides
900/8=112.5

4)first you count the sides
There are 7 sides

The equation of of finding the sum of all the interior angles is (n-2)*180
(7-2)*180
=5*180=900

To find the measure of one interior angles divide the answer by the number of sides
900/7= 128.57

Most small business owners put in extremely longhours and seldom take vacations. Although such firms later employ other workers, the management styleand personality of the owner seem to be necessary to the survival of the firm. Here are some examples.Ted and Ralph formed a partnership to operate a service station in a Prairie city. Both were on thepremises from 7 a.m. until closing at 8 p.m. Both were skilled at greeting the public and they made manyfriends as business boomed. Although they maintained ownership of the station, Ted and Ralph began tospend time away from work, leaving capable subordinates in charge. But the firm just wasnt the samewithout Ted and Ralph on hand, and business dropped. Ted and Ralph realized that to keep the stationhighly successful, they both had to be on the premises.For many years, Mabel and Theo Harker operated Harkers Cafe in a large city in the East. Theo was thechief cook, and Mabel waited on customers who sat at the counter. Although they hired several othercooks and waitresses, Mabel and Theo were the stable core of the business. The two worked long hours,and business seemed to go more smoothly when the owners were there. Realizing how important theywere personally to the success of the cafe, the Harkers never took a vacation and never left the cafe in thehands of the hired staff. Instead, in late summer and around Christmas, the Harkers closed down the entirecafe for a week at a time. Customers agreed that the place would not be Harkers Cafe without Mabel andTheo.1.

O philan Cox Enterprises Takes Cox Communications Private In an effort to take the firm private, Cox Enterprises announced a proposal to buy the remaining 38% of Cox Communications' shares not currently owned for $32 per share. Valued at $7.9 billion (including $3 billion in assumed debt), the deal represented a 16% premium to Cox Communication's share price at that time. Cox Communications is the third largest provider of cable TV, telecommunications, and wireless services in the U.S. serving more than 6.2 million customers. Historically, the firm's cash flow has been steady and substantial. Cox Communications would become a wholly-owned subsidiary of Cox Enterprises and would continue to operate as an autonomous business. Cox Communications' Board of Directors formed a special committee of independent directors to consider the proposal. Citigroup Global Markets and Lehman Brothers Inc. committed $10 billion to the deal. Cox Enterprises would use $7.9 billion for the tender offer, with the remaining $2.1 billion used for refinancing existing debt and to satisfy working capital requirements. Cable service firms have faced intensified competitive pressures from satellite service providers DirecTV Group and EchoStar communications. Moreover, telephone companies continue to attack cable's high-speed Internet service by cutting prices on high-speed Internet service over phone lines. Cable firms have responded by offering a broader range of advanced services like video-on-demand and phone service. Since 2000, the cable industry has invested more than $80 billion to upgrade their systems to provide such services, causing profitability to deteriorate and frustrating investors. In response, cable company stock prices have fallen. Cox Enterprises stated that the increasingly competitive cable industry environment makes investment in the cable industry best done through a private company structure. Discussion Questions: 1. What is the equity value of the proposed deal? 2. Why did the board feel that it was appropriate to set up special committee of independent board directors? 3. Why does Cox Enterprises believe that the investment needed for growing its cable business is best done through a private company structure? 4. Is Cox Communications a good candidate for an LBO?
