Answer:

Coordinates of B is (3,-4)

Step-by-step explanation:[tex]\frac{-7+x^{2} }{2}=-2[/tex]

[tex]\frac{2+y^{2} }{2} =-1[/tex]

You multiply -2 by 2 to get -4 and then create the equation [tex]-7+x^{2} = -4[/tex] then you substitue -7 for +7 and add +7 to -4 which gives you 3 (x coordinate of B)

You multiply -1 by 2 to get -2 and then create the equation[tex]2+y^{2} =-2[/tex] then you subtract 2 by -2 which gives you -4 (y coordinate of B)

To check your answer use the midpoint formula [tex]( \frac{x^{1} +x^{2}}{2} ) ( \frac{y^{1} +y^{2}}{2} )=M[/tex]

[tex]\frac{-7+3}{2} =\frac{-4}{2} =-2\\\frac{2+ -4}{2} =\frac{-2}{2} =-1[/tex]   which will give you the midpoint (-2,-1)

The required coordinate of the endpoint B is given as (3, -4).

A midpoint is a point on the line whose distance from both ends of the line is equal.

Here,
midpoints between any two points are given as,
x = x₁ + x₂ / 2    ; y = y₁ + y₂

since, the midpoint of AB is M(-2, -1). If the coordinates of A are (-7, 2),

So we have (x , y) = (-2, -1) and A(x₁, y₁) = (-7, 2), and to determine B(x₂, y₂)

Now.
x = x₁ + x₂ / 2    ; y = y₁ + y₂/2

-2 = -7 + x₂ /2  ; -1 = 2 + y₂ /2
x₂ = 3               ; -4

Thus, the required coordinate of the endpoint B is given as (3, -4).

Answer:

$96 is the original price of  book

Step-by-step explanation:

keep the unknown value as X

(19.2/X)*100 = 20%

19.2/X = 0.2

19.2/0.2 = X

X = 96

The original price of the book is $24.

When there is a sales, the price of items become cheaper. Items become less expensive when there is a sale.

When there is a 20% reduction in the price of the book, the book becomes 80% (100 - 20%) cheaper. In order to determine the original price of the book, divide the sales price by 80%

Original price = $19.20 / 80%

= $19.20 / 0.8

= $24

Answer:

[tex]x = A cos\theta[/tex]

Step-by-step explanation:

Given

Resultant Vector = A

Required

Determine the x component of vector A

To answer this question, I'll make use of the attachment

In the attachment, the relationship between A and the x component is as follows (using Pythagoras theorem):

[tex]cos\theta = \frac{x}{A}[/tex]

Multiply both sides by A

[tex]A * cos\theta = \frac{x}{A} * A[/tex]

[tex]A * cos\theta = x[/tex]

[tex]A cos\theta = x[/tex]

Reorder the equation

[tex]x = A cos\theta[/tex]

Hence, the x component of A is: [tex]Acos\theta[/tex]

Answer:

12.5 is to the nearest tenth

12.54 is to the nearest hundredth

Step-by-step explanation:

12.537

The first number after the decimal is the tenths place

we look at the number after it to determine whether to round up or down

12.53  the 3 is less than 5 so we leave it alone

13.5 is rounded to the nearest tenth

The second number after the decimal is the hundrdeths place

we look at the number after it to determine whether to round up or down

12.537  the 7 is greather than or equal to 5 so we round up

13.537  is rounded becomes 13.54

Answer:

Option (3)

Step-by-step explanation:

Given expression is,

(6 × 10⁸) ÷ (1.5 × 10⁻⁴)

We can rewrite the given expression as,

[tex]\frac{6\times 10^8}{1.5\times 10^{-4}}[/tex]

Now by solving this expression further,

[tex]\frac{6\times 10^8}{1.5\times 10^{-4}}=\frac{6}{1.5}\times \frac{10^8}{10^{-4}}[/tex]

             [tex]=4\times 10^8\times 10^4[/tex] [Since [tex]\frac{1}{10^{-4}} =10^4[/tex]]

             = [tex]4\times 10^{(8+4)}[/tex]

Glad I can help you!!

Answer:

Definition: The associative property states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or multiplying it does not matter where you put the parenthesis.

The word "commutative" comes from "commute" or "move around", so the Commutative Property is the one that refers to moving stuff around. For addition, the rule is "a + b = b + a"; in numbers, this means 2 + 3 = 3 + 2. For multiplication, the rule is "ab = ba"; in numbers, this means 2×3 = 3×2.

The value of exterior angle is 100

If a side of a triangle is produced, then the exterior angle so formed is equal to the sum of the two interior opposite angles.

Given:

angle 1 = 30

angle 2 = 7x

exterior angle= 10x

Now using exterior angle property

10x= 7x+30

3x= 30

x=10

Hence, the exterior angle is 10x= 100 degree

Answer: g(h(2))=8

Step-by-step explanation:

To find g(h(2)), you first need to solve h(2). After you find that value, you plug that value into g(x).

h(2)=2(2)-1                        [multiply]

h(2)=4-1                             [subtract]

h(2)=3

Now that we know h(2)=3, we plug 3 into g(x).

g(3)=3+5                            [add]

g(3)=8

After we have plugged in h(2) into g(x), we got g(h(2))=8.

Yes, she did not reverse the inequality sign when the last step was to multiply or divide by a negative number,

Step-by-step explanation:

Yes, Amanda make a mistake.

An error analysis on Amanda's work is in the last step, which is;

-1x ≤ -12 ⇒ x ≤ 12

The other student says that;

-1x ≤ -12 ⇒ x ≥ 12

Here,

Amanda was asked by her math teacher to solve an inequality on the board.

Amanda put the following on the board:

3x - 2(x - 1) ≤ 2x - 10

3x - 2x + 2 ≤ 2x - 10

1x ≤ 2x - 12

-1x ≤ -12

x ≤ 12

We have to find Amanda mistake to solve the inequality.

What is Inequality?

An inequality is a relationship between two expressions or values that are not equal to each other.

Now,

Amanda was asked by her math teacher to solve an inequality on the board.

Amanda put the following on the board:

3x - 2(x - 1) ≤ 2x - 10

3x - 2x + 2 ≤ 2x - 10

1x ≤ 2x - 12

-1x ≤ -12

x ≤ 12

Clearly, on last step Amanda make mistake to solve.

The correct solution is;

3x - 2(x - 1) ≤ 2x - 10

3x - 2x + 2 ≤ 2x - 10

1x ≤ 2x - 12

-1x ≤ -12

x ≥ 12

Hence,  Amanda make a mistake.
