What is the sum of the interior angles of the polygon?

Answer:

-2x^2+5x+12

Step-by-step explanation:

(4-x)(3+2x)

12-3x+8x-2x^2

12+5x-2x^2

-2x^2+5x+12

Answer:

f(5) = 0.5

Step-by-step explanation:

f (5) = 1.5(5) - 7

f (5) = 7.5 - 7

f(5) = 0.5

Answer:

Simplify first:

-4n - 20 = 8

Add 20 to both sides:

-4n = 28

Divide by -4:

Therefore you will get:

n = -7

Answer:

n = -7.

Step-by-step explanation:

-4(n + 5) = 8

-4n - 20 = 8

-4n = 28

n = -7.

Answer:

[tex] - (x - 1) {}^{2} + 5[/tex]

Step-by-step explanation:

F(x) is a transformation from h(x).

So our starting equation is

[tex] - (x - 1) {}^{2} - 1[/tex]

F(x) is also facing the same direction h(x) is so we dont have to reflect nothing across the x or y axis.

There isn't a vertical or horizontal stretch, compressions.

There isn't a horizontal shift as the x values stay in the same place.

There is a vertical shift. We can simply move h(x) up 6 units to get to f(x).

So our equation looks like.

[tex] - (x - 1) {}^{2} + 5[/tex]

Answer:

Rounded to the nearest dollar, Bob saved $677 by buying the carpet on Wednesday.

Step-by-step explanation:

Since on Tuesday, Bob brought home an oriental carpet on approval and the price in the store was 9900 Turkish Lira, but Bob was going to pay in dollars and, on Tuesday, one dollar was worth 4.5 Turkish Lira but on Wednesday, the Turkish Lira was devalued such that one dollar was now worth 6.5 Turkish Lira, with which Bob then bought the rug on Wednesday, paying the price of 9900 Turkish Lira with dollars at the new rate, to determine to the nearest dollar, how much did he save due to the devaluation the following calculation must be performed:

(9,900 / 4.5) - (9,900 / 6.5) = X

2,200 - 1,523.07 = X

676.92 = X

So, rounded to the nearest dollar, Bob saved $ 677 by buying the carpet on Wednesday.

Answer: x= 5

Step-by-step explanation: subtract 2x from both sides eliminating 2x.

4x-64=-44 add 64 to both sides eliminating -64

4x=20  divide by 4  

20/4 = 5

4x/4 = x

x= 5

Answer:

16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.

Step-by-step explanation:

Given that approximately 261,000,000 people live in the United States, and of these people 37,600,000 speak a language other than English at home, of which over 45 percent speak Spanish, to determine the number of people who speak Spanish in the United States, the following calculation has to be done:

37,600,000 x 0.45 = X

16,920,000 = X

261,000,000 = 100

16,920,000 = X

16,920,000 x 100 / 261,000,000 = X

6.48 = X

Thus, some 16,920,000 people speak Spanish at home in the United States, which represents 6.48% of the country's population.

Answer:

Equation: y = 2.5x

Answer: 43.75 drawers

Step-by-step explanation:

Equation: 10 - 7.5 = 2.5 and when you subtract 2.5 until the Number of Drawers (x) is 0, then you get 0 for Total Volume (y), so y =2.5x+0 or y = 2.5x

Answer: Substitute 17.5 into x.

y = 2.5(17.5)

y = 43.75 drawers

Answer:

x = 15 ft

Step-by-step explanation:

Triangle ACD is similar to triangle ABE based on the information given, therefore we can set up a proportion to compare the sides:

side AE / side EB = side AD / side DC

4/6 = 10/x

Solve for x

x = (10)(6) / 4

x = 60 / 4

x = 15 ft
