The expression using factoring is 4 * (33 + 57)+ 8)

The expression is given as

(132 + 228)

Factor out 2 from the expression

So, we have

(132 + 228) = 2 * (66 + !14)

Factor out 2 from the expression

So, we have

(132 + 228) = 2 * 2 * (33 + 57)

This gives

(132 + 228) = 4 * (33 + 57)

Hence, the expression using factoring is 4 * (33 + 57)+ 8)

Answer:  l=2w+3

Step-by-step explanation:

Using translation concepts, the graph of f(x) is given at the end of the answer.

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.

The parent absolute value function is given by:

f(x) = |x|

Which has the graph in the format of a V centered at the origin.

The translated function is given by:

g(x) = -1/2|x + 4| + 2.

The translations are as follows:

Answer:

  y = {-1/4 for x < -3; +1/4 for x > -3}

  see attached for a graph

Step-by-step explanation:

You want the function y = |x+3|/(4x+12) written as a piecewise function and graphed.

The absolute value function resolves into two pieces, each with its own domain. These let you write the function as a piecewise function.

When (x+3) < 0, the absolute value function negates this value:

  y = -(x+3)/(4(x+3)) = -1/4 . . . . . for x < -3

When (x+3) ≥ 0, the absolute value function does nothing. That means the equation becomes ...

  y = (x +3)/(4(x +3))

When the denominator is zero, the function is undefined. When the denominator is not zero, the function becomes ...

  y = 1/4 . . . . . for x > -3

Then the definition of the piecewise function is ...

  [tex]y=\begin{cases}-\dfrac{1}{4},&x < -3\\\dfrac{1}{4},&x > -3\end{cases}[/tex]

If the income is $54730 and state tax rate is 3.5% then the amount of tax that Erica Matthews needs to pay is $1915.55.

Given that the income is $54730 and state tax rate is 3.5%.

We are required to find the amount of tax that Erica Matthews need to pay.

State Government is basically tax that is levied by state government on the people living in that state.State governments basically use taxpayer dollars to fund road maintenance, law enforcement agencies and other public services.

Income=$54730

Tax rate=3.5%

Tax=54730*3.5/100       (We assumed that full amount is taxable.)

=$1915.55

Hence if the income is $54730 and state tax rate is 3.5% then the amount of tax that Erica Matthews needs to pay is $1915.55.

Josh start at 0 on the number line and mark 6 parts that are each 0.20.The product (6 *0.20) represents the total cost which is $1.20 .

A number line is a representation of numbers on a line with the marks  placed at the line at equal intervals. This marks or scale of line can be chosen as per our requirement.

For example if we scale the number line such that  each mark is placed at  an interval of number 1 then number 4 will come at 4th mark as each mark is at 1 unit distance with each other .

Given that josh buys 6 pencils at the bookstore and each pencil is of $0.20

Thus, the total cost of pencils = 6 * 0.20 = 1.20

Now on the given number line the numbers starting from 0 and ending at 2.4 and each one is at 2/10=0.2 intervals

Total marks on the line = ( final - initial number )/(length of each interval)

                                      = ( 2.4-0) /(0.2) =12

To find at how many marks total cost would be placed = total cost / interval length = 1.2 / 0.2 = 6

Therefore, when we start from 0 and at 6 marks at this number line our number value will 1.20 that is our total cost.

Answer:

  14.47 . . . units

Step-by-step explanation:

Given the vertices of triangle XYZ are (-1, 3), (3, 0) and (-1, -2), you want the perimeter rounded to hundredths.

The perimeter of a polygon is the sum of the lengths of the sides. When the points defining a side are on a vertical line, as with segment XZ, the length is the difference of y-coordinates.

When the points are not on a horizontal or vertical line, the distance between them can be found using the distance formula.

The distance between (x1, y1) and (x2, y2) is given by the formula ...

  d = √((x2 -x1)² +(y2 -y1)²)

The length of segment XY is ...

  d = √((3 -(-1))² +(0 -3)²) = √(4² +(-3)²) = √25 = 5

The length of segment YZ is ...

  d = √((-1 -3)² +(-2-0)²) = √((-4)² +(-2)²) = √20 ≈ 4.47

Side XZ has length (3 -(-2)) = 5, the difference of y-coordinates. Then the perimeter is ...

  P = XZ +XY +YZ = 5 +5 +4.47

  P = 14.47 . . . . units

The perimeter of the triangle is about 14.47 units.

The quotient of a number and -5 increased by 7 os at minimum 1 is x ≤ 30.

Sometimes they will ask for a remainder or to find a quotient using the dividend and divisor values. Whatever they ask for, you can quickly discover the right answer if you know how to write it down or how to build the equation based on reading the question.

Here, we assume that the quotient of a number is x, and we first write the formula by deciphering the provided question.

The product of a number's ratio to -5 and 7 is

x/-5 + 7

This is at least one

x/-5 + 7 ≥ 1

Take 7 away from both sides.

x/-5 ≥ -6

Add -5 to both sides. Since this integer is negative, the inequality sign must be changed:

The area of the polygon is equal to 10.006 square units.

In this case we find a polygon with four vertices, that is, a tetragon, also called quadrilateral. By geometry we know that quadrilaterals can be armed by uniting two triangles and the area of a quadrilateral is equal to the areas of the two triangles. Hence, the polygon NPQR is the result of combining the triangles NPQ and NQR.

First, determine the lengths of the sides of the two triangles:

NP = √[[3 - (- 2)]² + (1 - 1)²]

NP = 5

PQ = √[(3 - 3)² + [1 - (- 1)]²]

PQ = 2

NQ = √[[3 - (- 2)]² + (- 1 - 1)²]

NQ = √29

NR = √[[- 2 - (- 2)]² + [- 1 - (- 1)]²]

NR = 2

QR = √[(- 2 - 3)² + [(- 1) - (- 1)]²]

QR = 5

Second, calculate the areas of the two triangle:

s₁ = 0.5 · (NP + PQ + NQ)

s₁ = 0.5 · (5 + 2 + √29)

s₁ ≈ 6.193

A₁ = √[s₁ · (s₁ - NP) · (s₁ - PQ) · (s₁ - NQ)]

A₁ = √[6.193 · (6.193 - 5) · (6.193 - 2) · (6.193 - √29)]

A₁ ≈ 5.003

s₂ = 0.5 · (NQ + NR + QR)

s₂ = 0.5 · (√29 + 2 + 5)

s₂ ≈ 6.193

A₂ = √[s₂ · (s₂ - NQ) · (s₂ - PQ) · (s₂ - QR)]

A₂ = √[6.193 · (6.193 - √29) · (6.193 - 2) · (6.193 - 5)]

A₂ ≈ 5.003

A = 5.003 + 5.003

A = 10.006
