I need help with both questions 20 points

Answer:

[tex]x - y + 5 = 0[/tex]

Step-by-step explanation:

Given:

Required:

The equation of the line passing through two points is given by

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

So, [tex]\frac{y-3}{7-3} =\frac{x-(-2))}{2-(-2)}[/tex]

[tex]\frac{y-3}{4} =\frac{x+2}{2+2}[/tex]

[tex]\frac{y-3}{4} =\frac{x+2}{4}[/tex]

Now, [tex]y-3 = x+2[/tex]

On rearranging,

[tex]x - y + 3 + 2 = 0x - y + 5 = 0[/tex]

Therefore, the equation of the line is [tex]x - y + 5 = 0.[/tex]

Answer:

59 square inches.

Step-by-step explanation:

Equation for area of whole, large triangle:

A = 1/2(b)(h)

A = 1/2(13)(14)

A = 91 square inches

Equation for area of tiny, white triangle:

A = 1/2(b)(h)

A = 1/2(8)(8)

A = 32 square inches

Equation to find the area of the shaded region:

A = 91 - 32

A = 59 square inches

Answer:

64

Step-by-step explanation:

It's 64 because the area is the inside and 8 x 8 = 64.

Answer:

-2+2[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Since we have the value of x, 3+2[tex]\sqrt{2}[/tex], we can plug that value into the new equation.

We would recieve (3+2[tex]\sqrt{2}[/tex]-1)/3+2[tex]\sqrt{2}[/tex]

Which could simplify to -2+2[tex]\sqrt{2}[/tex]

[tex]x-\dfrac 1x\\\\\\=3+2\sqrt 2- \dfrac 1{3+2\sqrt 2}\\\\\\=3+2\sqrt 2 - \dfrac{3-2\sqrt2}{\left(3+2\sqrt 2\right) \left(3-2\sqrt 2 \right)}\\\\\\=3+2\sqrt 2 -\dfrac{3-2\sqrt 2}{3^2 - \left(2\sqrt 2 \right)^2}\\ \\\\=3+2\sqrt 2-\dfrac{3-2\sqrt2}{9-8}\\\\\\=3+2\sqrt 2-3+2\sqrt 2\\\\\\=4\sqrt2[/tex]

Answer:3.5

Step-by-step explanation: Check file

The probability that the sequence is guessed on the first try is 1/24

The given parameters are:

Colors = 4

Selection = 3

The first color can be selected from any of the 4, the second can be selected from any of the remaining 3 and the third can be selected from any of the remaining 2.

So, the number of sequence is:

Sequence = 4 * 3 * 2

This gives

Sequence = 24

Only one of these sequence is correct

Hence, the probability that the sequence is guessed on the first try is 1/24

To convert this equation into standard form simply expand the equation out using PEMDAS.

PEMDAS

To solve this question you must remember the order of PEMDAS

1) Parentheses

2) Exponents

3) Multiplication and Division

4) Addition and Subtraction

Expanding the Equation

Expand the binomial by raising (x+2) to the second power.

Next, using the distributive property, distribute the 3.

Then, combine like terms.

Answer:

x = 9

Step-by-step explanation:

You need to use PEDMAS (Parentheses, exponents, division, multiplication, addition, subtraction) to solve the equation.

1.) Begin by multiplying the values inside of the parentheses by the (-3).

2.) Isolate the variable by adding (15) to both sides.

2.) Isolate the variable by subtracting (2x) from both sides.

Starting Equation.)        2x - 6 = -3(5-x)

                            1.)       2x- 6 = -15 + 3x

                           2.)       2x + 9 = 3x

                           3.)        9 = x

Answer:

Median: 37

First quartile: 33.5

Third quartile: 40.5

Interquartile range: 7

Step-by-step explanation:

Your first step should be putting them in order from least to greatest.

27, 33, 34, 35, 37, 39, 40, 41, and 54. Now to find the median you have to find the middle which in the case would be 37. Now to find the 1st quartile u eliminate the meduan and focus on the lower half of the numbers which would be 27, 33, 34, and 35. If you numbers are even you add and divide by 2. In this case you have to add 34 and 33 and then divide by 2 since they are both in the middle. Your 1st quartile would be 33.5. To find the 3rd quartile you do the same thing as the 1st quartile. Only focus on the upper half now. add both the middles then divide by 2 since there are 2 middles. You 3rd quartile should be 40.5. To fine the inerquartile range you subtract the 1st quartile from the 3rd. so it would be 40.5-33.5 which would give you 7. If you want to fine just the range you would subtract the highest number from the lowest number.

Answer:

 =3y^2

Step-by-step explanation:

let,

       length: x

        width: y

According to condition,

      x = 3y   -----------(1)

Second condition

      Perimeter = 2 (l + b)

         80 = 2 (x + y)

         x + y = 40  -------------(2)

              To find area,

         Area = L x B

                    =3y x y

                     = 3y^2

Answer:

I think it is 4/9 pi r

Step-by-step explanation:

according to the condition given:

2nd cone has:

Height = 12cm

r= 1/3r (cause it's given 1/3 of radius of the original cone)

We know that volume of a cone is = 1/3 pi (r)^2 h

Now substitute the values:

1/3 * pi* (1/3r)^2 * 12

when u simplify u will get

pi* 1/9*r*4 = 4/9 pi r

So, the answer is probably 4/9 pi r.
