What is the area of this figure

Answers

So you basically have to find the area as if it were a rectangle, which would be 19*13, which is 247. Then, you find the area of the corner taken out and subrtact it, so 3*4 is 12, and 247-12 is 235.

11 x minus 3 y = negative 17. Negative 4 x + 3 y = negative 18. Negative 7 x = negative 35 Negative 7 x = 35 7 x = negative 35 7 x = 35

Answers

Answer:

7 x = -35

Step-by-step explanation:

Which equation results from adding the equations in this system? 11 x minus 3 y = -17. Negative 4 x + 3 y = - 18.

- 7 x = negative 35

- 7 x = 35

7 x = negative 35

7 x = 35

In this problem we need to add the equations below i.e.

11x-3y = -17 and -4x+3y=-18

Adding both equations,

11x-3y+(-4x)+3y = -17+(-18)

7x= -35

7 x = negative 35

Hence, the correct option is (c).

The graph below shows a company's profit f(x), in dollars, depending on the price of goods x, in dollars, being sold by the
company:

Part A: What do the x-intercepts and maximum value of the graph represent?
prefent? ?
Part B: What are the intervals where the function is increasing and decreasing, and what do they represent about the sale and
profit?
Part C: What is an approximate average rate of change of the graph from x = 1 to x = 3, and what does this rate represent?

Answers

Maximum value is maximum profit
The x intercepts are the prices that profit equals zero

B
Increasing from - infinity to 3 and decreasing from 3 to infinity. When price is less than 3 every increase in price results in an increase in profit. When price is greater than 3, every increase in price results in a decrease in profit. So what this is saying about sales is that when you set the price beyond 3 bucks, the amount of people willing the buy at that price drops such that you start making LESS profit because less people are willing to buy, and the lack of buyers offsets the additional price that the others are paying.

C
The average rate of change is 60 and this represents the increase in profit per increase in price

Answers

Answer:

n = 36

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , that is

AB = DC , substitute values

[tex]\frac{2}{3}[/tex] n - 5 = [tex]\frac{1}{3}[/tex] n + 7 ( multiply through by 3 to clear the fractions )

2n - 15 = n + 21 ( subtract n from both sides )

n - 15 = 21 ( add 15 to both sides )

n = 36

Answer:

n = 36

Step-by-step explanation:

AB = DC because it is a parallelogram

so:

2/3n - 5= 1/3n + 7

simplify by adding 5 to each side of the equation:

2/3n = 1/3n + 12

simplify by subtracting 1/3n from both sides of the equation:

1/3n = 12

multiply both sides of the equation by 3:

n = 36

I just heard about a great event that other cities are putting on, and I think Rockwood should, too. It is called Sunday Parkways, and it is a Sunday in the summer when whole neighborhoods are closed to cars. Only non-motorized vehicles and pedestrians are allowed. In other cities I have seen, people really get into the spirit of it. They play music and wear crazy makeup and costumes, and everyone has a blast, especially the kids. But the best part is that it brings the community closer together. People get to see and talk to their neighbors, and they often make new friends. At the end of the day, people feel energized and happy that they live in such a friendly town. Plus, it contributes to "greening" the city because everyone leaves their cars at home for the day. I think our city council should definitely consider putting on a Rockwood Sunday Parkways event.Sincerely,Serena BhattiWhich of these best summarizes the author's argument?A.
