factorize the expression​

Step-by-step explanation:

for each top equation, there is a y value and an x value. You could plug in the bottom equation for y in the top equation since y=5x+23. Then you do order of operations and get your y-value. Then you do order of operations again and get your x-value. then its ordered pair, (x,y)

[tex]-\frac{3}{2}[/tex]

Step-by-step explanation:

Given parameters:

Points = (1,1) and (5,-5)

Unknown:

Slope = ?

Solution:

The slope of the a line is the ratio of the rise of a line to its run.

 Slope  = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]  

x1  = 1

y1  = 1

x2  = 5

y2 = -5

  Insert the parameters and solve;

     Slope  = [tex]\frac{-5 - 1}{5-1}[/tex]   = [tex]\frac{-6}{4}[/tex]   = [tex]-\frac{3}{2}[/tex]

The number 211,647 rounded to the nearest thousand is 212,000. Hopefully this helps!

Answer:

212,000

Step-by-step explanation:

If we are rounding to the nearest thousand, lets take the first two digits and hide them. If we are rounding 1647 to the nearest thousand, it would be 2100. Then, add the first two digits back and now it is 212,000.

Answer:

The perimeter of a rectangle is the sum of both lengths and both widths, which is equal to 54 meters. Let's call Length L and Width W.

The question is saying this: L = 3 meters + 3(W). We have 2 variables, which means we need at least 2 equations to solve. So far we have one, our second equation is from the perimeter.

2 lengths + 2 Widths = 54. Now, it's just a plug and chug.

2(3 + 3W) + 2W = 54.

6 + 6W + 2W = 54

8W = 48

W=6

L = 3 + 3(6) = 21

To double check: 2(21) + 2(6) = 42 + 12 = 54

The Width is 6 meters, and the Length is 21 meters.

Answer: c) The distribution of the data tails to the left of the median

Step-by-step explanation:

In a scenario whereby the mean is more than the mode for a particular distribution, we can say that such distribution is said to be positively skewed.

Also, when the mean in the distribution is less than the mode, we can say that the distribution is said to be negatively skewed. For a negatively skewed distribution, it should be noted that on the left side, the tail of distribution is seem to be longer.

Therefore, the correct option is C "The distribution of the data tails to the left of the median".

The option C is correct.

So that Option C is correct.

Answer:

y = (x + 4)^2 - 3

Use Foil to solve (x + 4):

(x + 4)(x + 4) =  x^2 + 8x + 16

Plug it back into original equation:

y = x^2 + 8x + 16 - 3

y = x^2 + 8x + 13 is the answer :)

Step-by-step explanation:

Emily used an area model for 5,360 ÷ 5 split a rectangle into four parts: A=1,000, B=60, C=10, and D=2 units and total area = 5,360 after division the answer is 1,072.

To solve the division equation 5,360 ÷ 5, Emily used an area model split into 4 parts, each with a width of 5 units. Let's use the information provided to find the values of A, B, C, and D.

The area of the first part is 5,000 square units, and its width is 5 units. Therefore, the height of this part (A) is:

A = Area / Width

A = 5,000 / 5

A = 1,000 units

The area of the second part is 300 square units, and its width is 5 units. Therefore, the height of this part (B) is:

B = Area / Width

B = 300 / 5

B = 60 units

The area of the third part is 50 square units, and its width is 5 units. Therefore, the height of this part (C) is:

C = Area / Width

C = 50 / 5

C = 10 units

The area of the fourth part is 10 square units, and its width is 5 units. Therefore, the height of this part (D) is:

D = Area / Width

D = 10 / 5

D = 2 units

Now, we have the following values:

A = 1,000 units

B = 60 units

C = 10 units

D = 2 units

To find the total area of the rectangle, we sum up the areas of all four parts:

Total Area = 5,000 + 300 + 50 + 10 = 5,360 square units

Now, we can calculate the division 5,360 ÷ 5:

5,360 ÷ 5 = 1,072

Therefore, using area model the answer to the division equation is 1,072.

Answer:

When we divide 81 -x²y² by (9-xy) (3 + xy)​, we determine the expression is:

[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{9+xy}{3+xy}[/tex]

Step-by-step explanation:

Let us divide 81 -x²y² by (9-xy) (3 + xy)​

so

Given the expression

[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}[/tex]

Factor -x²y² + 81 = (9+xy) (9-xy)

[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{\left(9+xy\right)\left(9-xy\right)}{\left(9-xy\right)\left(3+xy\right)}[/tex]

Cancel the common term: 9-xy

                    [tex]=\frac{9+xy}{3+xy}[/tex]

Therefore, when we divide 81 -x²y² by (9-xy) (3 + xy)​, we determine the expression is:

[tex]\frac{81-x^2y^2}{\left(9-xy\right)\left(3+xy\right)}=\frac{9+xy}{3+xy}[/tex]

Answer:

1) [tex]\frac{(-2)^{-5}}{(-2)^{-10}}=-32[/tex]

2) [tex]2^{-1}.2^{-4} = \frac{1}{32}[/tex]

3) [tex](-\frac{1}{2} )^3.(-\frac{1}{2} )^2=-\frac{1}{32}[/tex]

4) [tex]\frac{2}{2^{-4}} = 32[/tex]

Step-by-step explanation:

1) [tex]\frac{(-2)^{-5}}{(-2)^{-10}}[/tex]

Solving using exponent rule: [tex]a^{-m}=\frac{1}{a^m}[/tex]

[tex]\frac{(-2)^{-5}}{(-2)^{-10}}\\=(-2)^{-5+10}\\=(-2)^{5}\\=-32[/tex]

So, [tex]\frac{(-2)^{-5}}{(-2)^{-10}}=-32[/tex]

2) [tex]2^{-1}.2^{-4}[/tex]

Using the exponent rule: [tex]a^m.a^n=a^{m+n}[/tex]

We have:

[tex]2^{-1}.2^{-4}\\=2^{-1-4}\\=2^{-5}[/tex]

We also know that: [tex]a^{-m}=\frac{1}{a^m}[/tex]

Using this rule:

[tex]2^{-5}\\=\frac{1}{2^5}\\=\frac{1}{32}[/tex]

So, [tex]2^{-1}.2^{-4} = \frac{1}{32}[/tex]

3) [tex](-\frac{1}{2} )^3.(-\frac{1}{2} )^2[/tex]

Solving:

[tex](-\frac{1}{2} )^3.(-\frac{1}{2} )^2\\=(-\frac{1}{8} ).(\frac{1}{4} )\\=-\frac{1}{32}[/tex]

So, [tex](-\frac{1}{2} )^3.(-\frac{1}{2} )^2=-\frac{1}{32}[/tex]

4) [tex]\frac{2}{2^{-4}}[/tex]

We know that: [tex]a^{-m}=\frac{1}{a^m}[/tex]

[tex]\frac{2}{2^{-4}}\\=2\times 2^4\\=2(16)\\=32[/tex]

So, [tex]\frac{2}{2^{-4}} = 32[/tex]

9/12 + 3/12 = 12/12 = 1

Therefore, 1 is your answer.

Answer:

Solving [tex]\frac{9}{12}+\frac{3}{12}[/tex] we get 1.

Option A is correct answer.

Step-by-step explanation:

We need to solve [tex]\frac{9}{12}+\frac{3}{12}[/tex]

For solving fractions we need to take LCM of denominators.

The LCM of 12, 12 is 12

So, solving:

[tex]\frac{9}{12}+\frac{3}{12}\\=\frac{9*1+3*1}{12}\\=\frac{9+3}{12}\\=\frac{12}{12}\\=1[/tex]

So, solving [tex]\frac{9}{12}+\frac{3}{12}[/tex] we get 1.

Option A is correct answer.
