K' ( -2, 2) , L' (1,2) , M' (1,-1) , N' (-2,-1)

Firstly, we needt to identify the coordinates of the vertices of the quadilateral

Afterwards, we then perform the translation

The translation simply means we add 2 to the x-value and add 4 to the y-value

So if we had coordinates of a vertex as (x,y); upon translation, we will have (x + 2, y+ 4)

Let us identify the vertices;

K'

K (-4,-2)

L (-1,-2)

M (-1,-5)

N (-4,-5)

After translation, we have;

Answer: I think the width is 7.

Step by step explanation:

So let's say the length is 12. This means I need to subtract 5 from it, since the width is 5 inches less than the length. Now that we know this, that means the width is 7, which is the area.

I hope this helps.

Using substitution method, the best initial step in solving the equation is solve the first equation for x.

The equation can be solved by substitution method as follows:

2x + 3y = -12

6x + y = 18

Hence, let's make y the subject of the formula in equation(ii)

6x + y = 18

y = -6x + 18

We have to substitute the value of y in equation(i)

2x + 3y = -12

2x + 3(-6x + 18) = -12

2x - 18x + 54 = -12

- 16x + 54 = -12

-16x = - 12 - 54

- 16x = -66

x = 66 / 16

x = 33 / 8

Therefore,

6(33 / 8) + y = 18

99 / 4 + y = 18

y = 18 - 99 / 4

y = - 27 / 4

From the solving above the best step to solve the equation is solving the first equation for x.

a.) The Assessed value is $43,830

b.) Annual Tax is $2,848.95

Define marked price

'Marked price' is the general price of the thing without any discount. 'discount' is a percentage of the marked price.

Given,

Assessment rate = 45%

Tax rate is $65 per $ 1000 of assessed value

Marked value = $97,400

a.)

To obtain assessed value,

calculate the 45% of $97,400 like that

45/100 = x/97,400

cross multiply the ratios

100x = 45 * 97,400

x = (45 * 97,400) / 100

x = 45 * 974

x = 43,830

Hence,the Assessed value is $43,830

b.)

Find yearly real estate tax,

Assessed value = $43,830

Tax rate is = 65 / 1000 of assessed value

                 = 0.065 * 43830

The expression, for example, x²- 49 may be factored as (x+7)(x-7).  can be factored in using the difference of squares identity.

The difference of the square's identity is shown below:

(a+b)(a-b) = a² -b²

When an expression can be seen as the difference of two perfect squares, i.e. a² -b², we can factor it as (a+b) (a-b).

For example, x²- 49 may be factored as (x+7)(x-7).

This approach is based on the pattern (a+b)(a-b) = a² -b², which may be validated by extending the parenthesis in (a+b)(a-b).

Thus, the expression, for example, x²- 49 may be factored as (x+7)(x-7).  can be factored in using the difference of squares identity.

Step-by-step explanation: The reason why is because in the question it said he is already carrying a 20 pound chair. It then say he can carry some boxes that weigh 5 pounds each. The word each is your keyword. With that you can replace the x variable with some single digit numbers. But you also need to make sure your total is less than or equal to 60 pounds. You would pick the less than or equal to sign since he can only carry 60 pounds or less.

Answer:

y= -3x + 5

Step-by-step explanation:

Answer: [tex]y=-4 \left(x-\frac{1}{2} \right)^2 +1[/tex]

Step-by-step explanation:

Using the vertex form, the equation is

[tex]y=a \left(x-\frac{1}{2} \right)^2 +1[/tex]

Substituting in the coordinates (2, -8) to solve for a,

[tex]-8=a \left(2-\frac{1}{2} \right)^2 +1\\\\-8=\frac{9}{4}a+1\\\\-9=\frac{9}{4}a\\\\a=-4[/tex]

So, the equation is [tex]y=-4 \left(x-\frac{1}{2} \right)^2 +1[/tex]

The example of an event which has a probability of 0 is probability of getting number 7 when you throw a die once. The probability of this event is zero because it will not occur.

The probability is the branch of mathematics that shows the occurrence of the random event. The value of the probability varies from 0 to 1.

The equation of the probability is

Probability = Number of favorable outcomes / Total number of outcomes

The probability of getting number number 7 when you throw a die once is zero. Because when you throw a die the possible outcomes are 1, 2, 3, 4, 5 and 6. We wont get number 7. Therefore the probability is zero

Hence, the example of an event which has a probability of 0 is probability of getting number 7 when you throw a die once. The probability of this event is zero because  it will not occur.

For the function f(x) =[tex]\sqrt{8x+10}[/tex] the inverse function [tex]f^{-1}[/tex](x) = [tex]\frac{x^2-10}{8}[/tex] x≥ 0 as can be calculated through the inverse function's formula.

In mathematics, any kind of inverse is a function that serves to “undo” any other function. That is, if f(x) produces y, then while putting y into the inverse off it produces the output x.

To find the inverse of a function, write the function y as a function of x i.e., y = f(x) and then solve for x as a function of y.

Inverse operations are seen as opposite operations that provides undo to each other. For example, 5 ✕ 2 = 10 and 10 ÷ 2 = 5 are inverse operations.

Every one-to-one function f has an inverse; this inverse is denoted by f−1 and read aloud as 'f inverse'. A function and its inverse 'undo' each other: one function does something, the other undoes it.

Answer:

348 ft

Step-by-step explanation:

First split the sidewalk into two rectangles. then multiply the LxWxH (length times width times height) of both rectangles. 8 times 6 times 6 = 288 ft. then 10 times 2 times 2 = 60. then add the two volumes of the rectangles to result in 348 cubic ft

The area of square is increasing with the rate of 144 cm/s2.

For physics, The term "thermal expansion" refers to a material's change in length, width, height, or volume when its temperature is raised or lowered. Solids exhibit particularly noticeable thermal expansion due to their closely packed atoms. There are numerous uses for thermal expansion of solids in daily life.

A solid's atoms vibrate more quickly around their fixed positions when it is heated. As a result, there is little relative growth in the size of solids during heating. In order to prevent buckling when exposed to heat from the sun, metal train tracks feature tiny gaps.

L = length of a side

A = L2

dA/dt = 2L dL/dt

dL/dt = 8 cm/s

A = 81 cm2 ⇒ L = √A = √81 cm = 9 cm

dA/dt = 2(9cm)(8 cm/s) = 144 cm/s2

Answer:

Speed of northbound train = 66

Speed of southbound train = 54

Step-by-step explanation:

First, let's make the variables simpler:

Speed of southbound train = x

Thus:

Speed of northbound train = y = x + 12

Distance = speed · time

240 = 2 ( x + x + 12 ) = 2 ( 2x + 12 ) = 4x + 24

216 = 4x

x = 54

Now, plug in x to find the speed of the northbound train (y):

y = 54 + 12 = 66
