6. P=4
7. M=7
8. N=13
9: Z= 5
10. X= 4
11. Y= 9

Answer:

6. p = 4

7. m = 7

8. n = 13

9. z = 5

10. x = 4

11. y = 9

Step-by-step explanation:

You can divide the solution by the number next to the letters/variables.

For example, to find 9p = 36 you can do 36 ÷ 9 which equals 4.

To double check, you can multiply your quotient by the divisor.

So to check if p = 4, you can do 9 x 4 which equals 36, therefore it is the solution.

Use the graph of the polynomial
function to find the factored form of
its related polynomial. Assume it
has no constant factor

Answers

Answer:

The factored form of the polynomial is [tex]y = (x-2)\cdot (x+1)[/tex].

Step-by-step explanation:

According to the graph, we have a second order polynomial with a vertical axis of symmetry. The standard form of the polynomial is:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex] (1)

Where:

[tex]x[/tex] - Independent variable.

[tex]y[/tex] - Dependent variable.

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Coefficients.

We can obtain the solution of the polynomial by knowing three distinct points. From graph we know that the curve pass through the following three points: [tex](x_{1},y_{1}) = (-1, 0)[/tex], [tex](x_{2},y_{2}) = (0, -2)[/tex], [tex](x_{3},y_{3}) = (2,0)[/tex]. Three linear equations are constructed:

[tex]a^{2}-b+c = 0[/tex] (2)

[tex]c = -2[/tex] (3)

[tex]4\cdot a + 2\cdot b + c = 0[/tex] (4)

The solution of this system is [tex]a = 1[/tex], [tex]b = -1[/tex] and [tex]c = -2[/tex]. Then, the polynomial in standard form is [tex]y = x^{2}-x-2[/tex]. By factorization, we find that factored form is:

[tex]y = (x-2)\cdot (x+1)[/tex] (5)

Answers

Answer:

1/2 ; 0 ; 2 ;

Step-by-step explanation:

3 / 8 to the nearest half

3/8 = 0.375

Using a number line, 0.375 is closer to 1/2 =0.5, than to 0 ; hence, 3/8 = 1/2(nearest half

2.) 2 /12 = 0.16666

2/12 = 0 (nearest 1/2)

3.) eight tenths plus nine tenths equals

8/ 10 + 9/10 = 17/10

17 /10 = 1.7

1.7 = 2 (nearest 1/2)

given: x+y=10 if x=-21, what is y?

Answers

Answer: y = 31

Step-by-step explanation: all you need to do is plug in the x

since x = -21 we can put: -21 + y = 10

now we add 21 to both sides giving us: y = 31

Answer:

(-21,22)

Step-by-step explanation:

x+y=10

x=-21

subtitue the x value

-21+y=2

solve for y

y=22

GCF: 2×2×2=8

b- 48+56=8(6+7)

Answer:

8(6+7)

Step-by-step explanation:

First, find the GCF of 48 and 56. The GCF of 48 and 56 is:

So the GCF, 8, will go outside the parenthesis. Then inside the parenthesis will be 48+56. Although first, you need to divide each of these by 8. So the numbers inside the parenthesis will actually be 6+7.

So the final answer is:

Answer:
Submit Answer

Answers

Answer:

0.053

Step-by-step explanation:

Using the compound formula A=P(1+r/n)^nt we can plug in the numbers we know. A being the total, P the initial amount, n is the number of compounds in a year, and t is the number of years passing. So 10300= 4900(1+ r/12)^12(14). We have to isolate r in order to find the rate. We can divide both sides by 4900, giving us 103/49= (1+ r/12)^168. Then we take the 168 square root from both sides. 1.00443… = 1 + r/12. Subtract 1 from both sides. 0.00443… = r/12. Then multiply both sides by twelve . r= 0.053

Why or why not? The m Sear Seart Sease Nike sineios In the 1800s, the United States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development of society following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developments caused a rapid growth in American urban areas. Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. The abundance caused food prices to fall. The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work in northern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today, the need for work is a common reason people move to urban areas. As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization. In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities with more than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia and New York City were the most populated cities in 1860 and would soon reach one million residents. The urbanization of the United States quickened due to technology improvements. Without innovations in food production, the factories could not have grown so quickly. The trend quickened after 1860 and continued throughout the 21st century as well. By 2007, more Americans lived in or near cities than they did in rural areas. Select a sentence from the body of this article that can be removed without affecting the author's explanation.
