Step-by-step explanation:

the area is 20.37 if u need the steps just add a comment and ill show the steps

Answer:

In bold.

Step-by-step explanation:

a.  (x+5)^2 – 3x(x+5)     x+5 is common

= (x + 5)(x + 5 - 3x)

= (x + 5)(5 - 2x)

b.  (x + 5)(5 - 2x) = 0

x = -5, 2.5.

2a.   Area of the square = (x + 5)^2

Area of triangle AEB

= 1/2 * base * height  

I am assuming that  H is the centre of AB , so

Area = x*x

= x^2.

2b

6x^2 = (x + 5)^2

6x^2 = x^2 + 10x + 25

5x^2 - 10x - 25 = 0

x^2 - 2x - 5 = 0

x = [-(-2) +/- sqrt(2^2 - 4*1*-5)] / 2

x = -1.45, 3.45.

 (we ignore the negative).

Answer:

y=4-0.5x

Step-by-step explanation:

Step one:

given data

Alina bought an ice cream cone for $3

the weight of the ice cream is 4 ounce

the rate of melting is 0.5 ounce per minute

let the number of minutes taken for the ice cream to melt be x

and the weight after x minutes be y

Step two:

Hence the expression for the situation after x minutes is

y=4-0.5x

The value of 60 milligrams after unit conversion is 0.00006 Kg.

A unit conversion expresses the same property as a different unit of dimension. For case, time can be expressed in twinkles rather of hours, while distance can be converted from long hauls to kilometers, or bases, or any other measure of length.

A conversion factor is an expression for the relationship between units that's used to change the units of a measured volume without changing the value.

We have to convert 60 mg to Kg.

As, 1 Kg = 1000 g

and, 1 gm = 1000 mg

So, 1 mg = 1/ 1, 000, 000 Kg

Then, the conversion is

= 60 / 1, 000, 000

= 6/ 100,000

= 0.00006 Kg

Answer:

quadratic functions have a vertex

Answer:

3p³ + 5p² - 8

Step-by-step explanation:

Given:

6p - 2

-6(-p-1) = 6p + 6

Subtract 6p + 6 from 3p³ + 5p² + 6p - 2 get your answer

= 3p³ + 5p² + 6p - 2 - (6p + 6)

= 3p³ + 5p² + 6p - 2 - 6p - 6

= 3p³ + 5p² - 8

3p³ + 5p² - 8 Should be added To -6(-p-1) to get 3p³+5p²+6p-2

Answer:

Please check the explanation.

Step-by-step explanation:

We know that the slope-intercept of the line equation is

[tex]y = mx + b[/tex]

where m is the slope and b is the y-intercept

Please note that a linear equation contains no powers of x besides.

For example, the equation of the form

y = 2x+3

has the slope m = 2 and y-intercept b = 3

The graph is shown below.

Let us graph two more functions of the same family by changing the parameter of y-intercept b.

Graphing y = 2x+5

y = 2x + 5

has same slope m = 2. But, the y-intercept b = 5

The graph of y = 2x+5 is attached below.

Graphing y = 2x+7

y = 2x + 7

has same slope m = 2. But, the y-intercept b = 7

The graph of y = 2x+7 is attached below.

Thus, we would have the following graphs of the family of linear functions.

Please notice that all the functions have the same slope m = 2. Thus, all the lines would be parallel.

Thus, from the graph, it is clear that:

The graph is attached below.

I did the question in class today. I hope this helped!

Given:

The image of point A under a 90° rotation about the origin is A'(10, -4).

To find:

The coordinates of point A.

Solution:

90° rotation about the origin means the figure is rotated 90° counterclockwise about the origin and the rule of rotation is

[tex](x,y)\to (-y,x)[/tex]

Let the coordinates of A are (a,b).

[tex]A(a,b)\to A'(-b,a)[/tex]

The image of point A under a 90° rotation about the origin is A'(10, -4).

[tex]A'(-b,a)=A'(10,-4)[/tex]

On comparing both sides, we get

[tex]-b=10\Rightarrow b=-10[/tex]

[tex]a=-4[/tex]

Therefore, the coordinates of point A are (-4,-10).

Answer:

a = -

b = -

c = 9

d = 3

e = 3

f = 2

Step-by-step explanation:

First we will solve the expression:

[tex]\frac{3x}{2x-6}+\frac{9}{6-2x}[/tex]

Solving:

First we will take negative sign common, then take LCM of denominator and simplify the expression.

[tex]=\frac{3x}{2x-6}+\frac{9}{\textbf{-}(2x-6)}\\=\frac{3x}{2x-6}+\frac{\textbf{-}9}{(2x-6)}\\Taking\:LCM\\=\frac{3x-\mathbf{9}}{2x-6}\\=\frac{\mathbf{3}(x-\mathbf{3})}{\mathbf{2}(x-3)}\\=\mathbf{\frac{3}{2}}[/tex]

So, After solving we get:

a = -

b = -

c = 9

d = 3

e = 3

f = 2

Answer:

x >_ - 7

Step-by-step explanation:

Answer:

We conclude that the range of the function will be:

R = {5, 17, 29}

Step-by-step explanation:

Given

Given the function

f(x) = 6x-1

Given the domain

D = {0, 3, 5}

To Determine:

The range R = ?

We know that range of the function consists of all the y-values for the x-values in the domain of the function.

so substituting the values of x = 0, 3, and 5 in the function to determine the corresponding y-values.

Plug in x = 0

y = 6x-1

y = 6(0) - 1 = 6-1 = 5

Plug in x = 3

y = 6x-1

y = 6(3) - 1 = 18-1 = 17

Plug in x = 5

y = 6x-1

y = 6(5) - 1 = 30-1 = 29

Now, combine all the determined y-values which are 5, 17, and 29.

Therefore, we conclude that the range of the function will be:

R = {5, 17, 29}
