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

A piece of land is 8 1/2 miles wide. It is 4 7/8 times as long as it is wide. How long is the piece of land.
Answer:
[tex]Length = 41\frac{7}{16}[/tex]
Step-by-step explanation:
Given
[tex]Width = 8\frac{1}{2}[/tex]
[tex]Length = 4\frac{7}{8}[/tex] times as long as the width
Required
Determine the length
To do this, we simply multiply the length by [tex]4\frac{7}{8}[/tex]
So, we have:
[tex]Length = 4\frac{7}{8} * Width[/tex]
Substitute [tex]8\frac{1}{2}[/tex] for width
[tex]Length = 4\frac{7}{8} * 8\frac{1}{2}[/tex]
Convert to improper numbers
[tex]Length = \frac{39}{8} * \frac{17}{2}[/tex]
[tex]Length = \frac{39*17}{8*2}[/tex]
[tex]Length = \frac{663}{16}[/tex]
[tex]Length = 41\frac{7}{16}[/tex]

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

Step-by-step explanation:
1) a) Factorize: G(x) = (x+5)2 – 3x(x+5).
b) Solve G(x) = 0.
2) In the adjacent figure ABCD is a square:
a) Express the area of the square and the area
of triangle AEB in terms of x.
b) Calculate x so that the area of the square is equal
to 6 times the area of triangle AEB.
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).

Alina bought an ice cream cone for $3. Her 4- ounce scope of ice cream is melting at rate of 0.5 ounces per minutes. Write an equation to represent the amount of ice cream left after x minutes.
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
A pack of pencils contain a dozen pencils.450 such packs were put in a carton. If there are 25 such cartons, find the total number of pencils.
Answer:
135000
Step-by-step explanation:
Given: A pack of pencils contain a dozen pencils. 450 such packs were put in a carton. There are 25 such cartons.
To find: total number of pencils
Solution:
Total number of pencils in a pack = 1 dozen = 12
Total number of packs = 450
Total number of cartons = 25
Total number of pencils = 12 × 450 × 25 = 135000
So, total number of pencils is 135000.

Step-by-step explanation:
First we will solve the expression:

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]

Graph two more functions in the same family
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.
y = 2x+3y = 2x + 5y = 2x + 7Please 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 red line represents the function y = 2x+3 with the y-intercept (0, 3)The blue line represents the function y = 2x+5 with the y-intercept (0, 5)The green line represents the function y = 2x+7 with the y-intercept (0, 7)The graph is attached below.

60 milligrams = ______ km
The value of 60 milligrams after unit conversion is 0.00006 Kg.
What is Unit Conversion?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
