Answer:x=10

Step-by-step explanation:

Answer:

x=10

Step-by-step explanation:

Multiply the numbers

2⋅3x=[12(4x+20)]⋅22⋅3=[12(4+20)]⋅2

6x=[12(4x+20)]⋅26=[12(4+20)]⋅2

Combine multiplied terms into a single fraction

6x=[12(4x+20)]⋅26=[12(4+20)]⋅2

6x=[1(4x+20)2]⋅26=⎣⎡1(4+20)2⎦⎤⋅2

Multiply by 1

6x=[1(4x+20)2]⋅26=⎣⎡1(4+20)2⎦⎤⋅2

6x=[4x+20/2]⋅26=[4+20/2]⋅2

Re-order terms so constants are on the left

6x=4x+20/2⋅26=4+20/2⋅2

6x=2⋅4x+20/2

Cancel multiplied terms that are in the denominator

6x=2⋅4x+20/2

6x=4x+20

Subtract 4x from both sides

6x=4x+20

6−4=4+20−4

Simplify

6x-4x=4x+20-4x

2x=4x+20-4x

Combine like terms

2x=20

Divide both sides by the same factor

2x=20

2x/2=20/2

cancel 2 on both sides

20 divided by 2 is 10

so therefore,

x=10

The range of the given relation is (-6, -3, 0, 3, 6).

Range:

Basically the set contains 2 elements in it, in which set contains all the second elements, on the other hand, is known as the range of the relation.

Given,

Here we have the relation (-5,6), (-3,3), (-1,0), (1,-3) and (3,-6)

Here we need to find the range of the relation.

According to the definition of the relation,

Range refers the y values of the coordinates,

So, based on this the value of the given coordinates are extracted as,

(-5, 6) => 6

(-3, 3) => 3

(-1, 0) => 0

(1, -3) => -3

Translation 1 unit up is the transformation which accomplish the graph.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

Figure C is the result of a transformation on Figure B

We need to find which transformation is used for this.

Graph transformation is the process by which an existing graph, or graphed equation, is modified to produce a variation of the proceeding graph.

and  A vertical reflection reflects a graph vertically across the x-axis, while a horizontal reflection reflects a graph horizontally across the y-axis

Horizontally translating a graph is equivalent to shifting the base graph left or right in the direction of the x-axis.

By first subtraction b and then dividing by m, the solution of the linear equation for x is:

(y - b)/m = x

Here we have a linear equation that defines the variable y in terms of the variable x:

y = m*x + b

Where m and b are real numbers.

Now we want to find x in terms of the variable y, this means that we need to isolate the variable x.

if first we subtract b in both sides, we get:

y - b = m*x + b - b

y - b = m*x

If now we divide both sides by m, we get:

(y - b)/m = m*x/m

(y - b)/m = x

Answer:If you’re using imagine math it will be the the third one

Step-by-step explanation:

To calculate the p-value, we have to follow the following steps:

To calculate the p-value, we need

p = sample proportion

p' = assumed population proportion in the null hypothesis

n = sample size

Example

Given, n =40, σ = 32.17 and X = 105.37. calculate p-value.

σₓ = σ/ √n

σₓ = 32.17 / √40

    = 5.0865

Now, by applying the test static formula, we get

t = (105.37 – 120) / 5.0865

t = -2.8762

Using the table, we find the value of P(t>-2.8762)

From the table, we get

P (t<-2.8762) = P(t>2.8762) = 0.003

If P(t>-2.8762) = 1- 0.003 = 0.997

Using front end estimation, the solutions to the given problems are;

1) 25.72

2) 137.521

3) 17.1

Front-end estimation is defined as a particular way of rounding numbers to estimate sums and differences.

The procedure for using front- end estimation, is to add or subtract only the numbers in the greatest place value. Thereafter, we add the decimals rounded to the nearest tenth.

1) 32.47 - 6.75

First of all, let's deal with the whole numbers part;

32 - 6 = 26

Next is to deal with the decimal part to get;

0.47 is approximately 0.5 while 0.75 is approximately 0.8. Thus;

0.5 - 0.8 = - 0.3

Thus, we have;

26 + (-0.3) = 25.70

Therefore, our given solution can be written as; 25.72

2) 118.234 + 19.287

The width of the enlarged photo is 12 inches

The length of the original photo = 10 inches

The width of the original photo = 8 inches

The length of the enlarged photo = 15 inches

The width of the enlarged photo = x

10 / 8 = 15 / x

Cross multiply the terms

10x = 15 × 8

Multiply the terms in the equation
10x = 120

Divide both side of the equation by 10

10x / 10 = 120 / 10

The minimum measurement is 12.85 and the maximum measurement is 12.94 that would be equal to 12.9.

What is rounding of decimal numbers?

Look at the next digit in the correct position to determine how to round a number; if it is less than 5, round down, and if it is 5 or more, round up. The term "rounding decimals" describes the accurate rounding of decimal figures. To the nearest whole, tenth, or hundredth, we can round decimals.

Given, An ostrich egg has a width of 12.9 cm to the nearest tenth of a centimeter.

We have to find the minimum and maximum possible measurements.

If you're rounding to the nearest tenth of a centimeter, 12.85 centimeters is the smallest measurement that would equal 12.9 centimeters.

And 12.94 centimeters is the maximum measurement that would be equal to 12.9.

Therefore, the minimum measurement is 12.85 and the maximum measurement is 12.94.

Answer:

Step-by-step explanation:

Step-by-step explanation:

the highest exponent is 2, so, we expect to get 2 factors in x (as the multiplication of x×x = x²).

3 is a prime number, and the only factors to get 3 are 3 and 1

3 = 3×1

so, we expect to get factors that look like

(3x + a)(x + b)

when we do the multiplication, we get

3x² + 3bx + ax + ab = 3x² +(3b + a)x + ab

now we compare this to our original expression

3x² +(3b + a)x + ab = 3x² - 13x + 12

3b + a = -13

ab = 12

so, we know a and b must both be negative

(-×- = +, - - - = -).

the negative factors of 12 are

-12 × -1

-6 × -2

-4 × -3

which one of these pairs can make

3b + a = -13

3×-12 + -1 = -37 no

3×-1 + -12 = -15 no

3×-6 + -2 = -20 no

3×-2 + -6 = -12 no

3×-4 + -3 = -15 no

3×-3 + -4 = -13 yes

Answer: 2x3-1

Step-by-step explanation:

Five minutes into the descent the airplane has an altitude of 500 feet.

Given that an airplane at 3,000 feet begins to descend at a rate of

500 feet per minute, it is required to write an equation to model the situation and find the altitude of the airplane after 5 minutes.

First, we can model the situation through a linear equation of the form

y = mx + b.

Then, we must identify each variable:

y = A = Altitude

m = decrease per minute = 500

x = t = minute-time

b = Airplane height = 3,000

Now, we set up the equation, substituting y, m, x, and b into the linear equation, as the situation models the descent of the airplane the slope must be negative; thus:

A(t) = 3,000 − 500t

Lastly, we must find the altitude when if t = 5:

A(5) = 3,000 − 500(5)

Solving, we obtain:

A(5)=3,000 − 2,500 = 500

Hence the answer is, Five minutes into the descent the airplane has an altitude of 500 feet.
